Restores the orc breeding pits cut content to the game. This is the original completely unaltered orc breeding pits, just as objectionable as it was in version 1.1.3, before any changes were made. You have been WARNED. Do not complain about the potentially objectionable content.

Various enhancements to escort quest NPCs:
- Escorts now follow the player when not close to the portal.
- Escorts occasionally say useful things.
- Escorts heal 5% of their maximum health per turn.

Adds Embers of Rage races for use in the Maj'Eyal Campaign. Currently they all start in the Trollmire, Allied faction, with the default Human quest. Suggestions for that stuff is welcome.

DarkGod pretty much showed me how to do this, so thank you!

Yeti/Whitehoof will be locked unless you've unlocked them in the Embers of Rage DLC.
Embers of Rage DLC is required for this to work!

I'm still new at this, so let me know if there are any issues and I'll try to sort them out.

V1.0.1 is up, I wasn't paying attention when I did it through TOME so I just got rid of the old version. This version should hopefully add in the random escort quests for the three races, since they weren't defined before.

Attempts to make minion necromancer builds a bit more fun, while keeping it relatively balanced.

Necrotic Minions

Necrotic Aura - increased decay rate by 5%.
Aura Mastery - max radius is increased to 10.
Dark Empathy - is now tier 3.
Surge of Undeath - is now tier 4; has better scaling.

Necrosis

Lichform - increases necrotic minions mastery by 0.1 at talent lv 3 and 0.2 at lv 5.

Shades

Shadow Tunnel - evasion duration increases with talent points.
Curse of the Meek - minor cosmetic change (less likely to summon bunnies).

Advanced Necrotic Minions

Undead Explosion - damage type depends on the minion used. Credit goes to HousePet.

Minion Mastery - Vampire minions have the same talents as enemy vampires. Wights have talent masteries like enemy wights. Barrow wights are replaced with emperor wights. And dreads are replaced with dreadmasters.

Animus

Is now a generic tree.

Many in Maj'Eyal have heard of "demons", sadistic creatures who appear seemingly from nowhere, leaving a trail of suffering and destruction whereever they go. Their Fearscape floats far above the skies, watching and waiting, but not idly; their agents scout the land, their legions build up their forces, and their scholars develop new spells and strategies. As the barrier between our worlds begins to crack under their scrutiny, helpless Eyalites have begun to disappear, whisked up to serve as their slaves and playthings. They imbue these victims with magical powers to better survive the ensuing stresses - can you use your new-found abilities to escape the legions of Mal'Rok?

Features:

• Start with a new class, the Doombringer! These avatars of demonic destruction charge into battle with massive two-handed weapons, cutting swaths of firey devastation through hordes of opponents. Armed with flame magic and demonic strength, they delight in fighting against overwhelming odds, softening up the crowd with waves of fire, then feeding on the flames and suffering of their surroundings to stay alive while quickly reducing any group to a pile of ash and gore.
• Unlock a new class, the Demonologist, with an all-new item enhancement mechanic! Bearing a shield and the magic of the Spellblaze itself, these melee-fighting casters can grow demonic seeds from their fallen enemies. Imbue these seeds onto your items to gain a wide array of new talents and passive benefits, and summon the demons within them to fight on your side! Ever looked at a gigantic demon-cursed minotaur and wished it was on your side for once? Well, now you CAN summon one to pound your foes into paste while you cast devastating spells from afar, or call forth a squad of Fire Imps to pelt your enemies to death while they exhaust themselves on your impenetrable defenses! Demons have persistent health, making them a little more precious than disposable necromancer skeletons or summoner beasts, but can be revived from death nonetheless.
• Two new zones, with all-new art, foes, and bosses! You've seen the plains of the Fearscape before, now see the lairs and headquarters of the demons themselves!
• Over 10,000 words of written lore to find! The demons were once an enlightened, peaceful race, hailing from a distant planet known as Mal'Rok; learn what drove them to plot Eyal's eternal torture! Discover monuments to each of the demonic species and noteworthy individuals, showing the place of honor each has among them! Get a glimpse into the culture and daily lives of these sadistic invaders and their brainwashed thralls!
• Unlock a new race, Doomelves: Shalore who've taken to the demonic alterations especially well, corrupting their typical abilities into a darker form. Blink away to safety, transform into a shadowy dúathedlen to hide in the shadows or prey on your foes with blasts of darkness, use your new resilience to soak up status effects and critical hits, and assault your enemies' minds to leave them unsteady in combat!
• Between the aforementioned classes and Doomelves, a whopping 75 new talents!
• Unlock two new cosmetic options! You know you've always wanted demon-horns.
• Two new events, appearing anywhere in Eyal!
• 20 new artifacts, with unique and interesting effects. Collect the Obsidian Treasures to amass more and more power! Slip your hands into the Will of Ul'Gruth and watch your sweeping blows smash down walls! Wear a giant hideous hell-mouth as a fashionable belt!
• 7 new achievements! Conquer the worst Urh'Rok's forces can throw at you, and hang their metaphorical skulls from your profile page!

Places the Sect of Kryl-Feijan event on the map as a zone entrance rather than an undetectable encounter.

Do you dislike it, when your escortees die on harder difficulties at the zone in, without you being able to help them? Do you sometimes feel as if money was worth little to nothing in Maj'Eyal? If so, this addon might help you. The library of Last Hope now sells seven Tomes with on-use-rewards, that mirror those of seven escort-types. The library of Elvala sells two (very expensive) tomes, that lead to even greater rewards after using them.

Fixed: talent types are now known, but not learned

A collection of tweaks for existing ToME content.

About:
Well, in Rogue-like games I enjoy replayability with loot and unlocks found by previous characters. But in this game a shared vault bound to donations and have a lot of restrictions placed on it. So what? I'm a programmer myself :)

After half a day diving in documentations and source code of other addons (original Items Vault included) this is what I managed to put together.

Shared Stash features:
- Shared between ALL characters
- Accessible through main menu in ANY type of game
- NO forced lvl restriction placed on items
- NO forced cooldown to take your items back
- Still prevent from putting "illegal", plot and etc. items to not spoil the game
- You still can use official Items Vault addon with no known issues
- NO need to pay me. "Thanks" is enough :)

From Russia with love.

Changelog:
Addon Verision 1.1.0
- Upgraded item list interface. Created "Category", "Tier", "Enc." columns for more usability.
Addon Verision 1.0.1
- Minor UI text fixes
Addon Verision 1.0.0
- Initial Release

The Cornac talent category point isn't something they gain over the other races. They just don't auto-spend it on a racial talent category because they don't have one. Now Cornac's can actually have more talent categories than anyone else.

Removes certain ambient sound effects:
-Barking dogs in towns
-Howling wolves in dungeons
-Eagle screeches

This adds the Spell/Conveyance tree as a reward for completing the Tempest Peak questline for Angolwen. All the code is borrowed from DG's own, and thus everything works the same as antimagic characters getting Fungus.

EDIT - I'm thrilled that this actually became obsolete less than a day after putting it up. I'll leave this up in case someone needs it (I guess if you like the cultists and don't have Ashes this should fix their spawn rate for you too).

This fixes the spawn chance of the Cultists/Monolith event needed to summon Shasshhiy'Kaish and complete the Doom Elf unlock

Increases the mastery value increase to 0.4, and removes the 1 increase limit.

Modifies the character creation dialog to bypass the lock check for races and classes, allowing characters to be created using locked races and classes. Doesn't actually unlock anything.

Frequently Asked Questions:

• Hey, the character creation dialog still says I have locked races/classes! What gives?
• Will this prevent me from unlocking things?
• The latest version of the game has a new locked race/class. Will I need a new version of this addon to access it?
• What the heck is this Runic Golem thing?

One year has passed since the one the Orcs call the "Scourge from the West" came and single-handedly crushed the Orc Prides of Grushnak, Vor, Gorbat, and Rak'Shor.  The Allied Kingdoms, now linked by farportal to their distant, long-lost Sunwall allies, have helped them conquer most of Var'Eyal.  The few remnants of the ravaged Prides are caged...  but one Pride remains.  Kruk Pride, isolated on an island, is the last orcish settlement that stands; they, too, face their impending doom.  The Sunwall has blockaded the only exit point from the island, and now, the technologically advanced civilization of Steam Giants have come down from the mountains to take their homeland with machines and weaponry unlike anything else on Eyal.  Kruk Pride has reverse-engineered their technology before; their only hope is to do it again and rise up against the Pride's foes.
 

Features:

• Explore a whole new campaign from level 1 to 50, one year after the events of the original Tales of Maj'Eyal campaign. Liberate the Orcs (or die trying) by rising up against the Sunwall, the Steam Giants of Atmos, and other dangers that may lie in wait...
• Play as one of three new races: the battle-hardened Orcs, the brutal Yetis, and the unstoppable Whitehooves. Discover their stories, their pains, their hopes... and their awesome racial powers!
• Risk your life in over 20 unique zones! Explore the ruins of a lost city, lay siege to the Sunwall forces at the Gates of Morning, and raid the Steam Giants' mining quarry - each has its own unique foes and hazards, leading each to feel and play different from the others.
• Play as one of the four new tinker classes: Gunslingers, Sawbutchers, Psyshots and Annihilators! Plus a class evolution: Technomancers! Crush and rend your foes with heavy metal, electrocute and immolate them with your gadgets, charge across the battlefield or nimbly strafe in style - each plays differently, and none provide any shortage of ways to slay your foes.
• Master steam technology to build powerful tinkers to augment your equipment. Need to close in a bit quicker? Turn your boots into rocket boots! Having a hard time deciding whether to shoot someone or stab them? Build a Hand Cannon into your gloves, or deploy a Weapon Automaton to do the stabbing for you! If you have a problem, steamtech has a solution, usually involving explosions; with over 80 different powerful contraptions to craft, enjoy unparalleled versatility and trying something different with every playthrough.
• Master the tactical uses of over 140 talents! Fire bouncing trick-shots and psychic-infused shots, use your steamsaws as shields or wheels, terrify your foes with long mechanical arms - there are no "boring" talents here, everything has its own special applications and properties!
• Use advanced technology in the world of Eyal! Burrow through sand, plant bombs to destroy tunnels, and discover that you aren't alone in using it...
• Infusions and runes are for puny humans; implant new medical injectors to pump an array of experimental chemicals into your body! Injectors can use any (infinitely reusable) salve in your inventory as long as they're off their cooldown, giving you versatility you've wished you could get with a couple of inscriptions.
• Loot over 70 new and powerful artifacts. Pump lead into foes with big guns, quick guns, and explosive guns! Shred them with saws that maim, saws that thirst for blood, and saws that aren't really saws! Violate common sense by strapping a rocket to your back and calling it a jetpack!
• Enjoy dying in horrible and exotic ways at the hands (or claws, jaws, guns...) of over 140 new creatures! Not mere piles of stats and chain-stuns, these foes will provide unique challenges - suffer the Sunwall's newest cosmic spells, the new breeds of ritches that infest and multiply, the Steam Giants' elaborate defense systems, and find new strategies to adapt to each!
• Earn a trunkload of achievements! Have your accomplishments recognized for liberating the Orcish people, displaying exceptional mercy or cruelty, or showing your prowess with impressive feats! Give a boss a fate worse than death, show Sunwall forces how frustrating it is to fight a Radiant Horror as a paladin, come out on top against impossible odds, display a suicidal lack of situational awareness, and wear a badge of pride or shame for each!
• Read roughly 27,000 words of new lore to immerse yourself in the world! Learn how things have changed since the Scourge's campaign, feel hatred and/or pity for your foes, uncover grand schemes and sinister plots, and notice the elaborate connections between Var'Eyal's numerous factions. Every zone has a story behind it, and every story ties into a bigger picture; enjoy a tale of horror and humor, of intrigue and glory, of despair and hope.
• Earn the right to use the classic (and Ashes of Urh'Rok) classes in Embers of Rage, and the new tinker classes in Maj'Eyal! Play a Brawler in the East to fulfill your life-long dream of suplexing an entire nation of giants, or play a Sawbutcher in Maj'Eyal to shred through Dreadfell in a whirlwind of sawblades and steam!

The addon you hope you never have to use.

If all goes well, you never have to touch it. Behind the scenes, BGA monitors the location of every NPC on the current map level.

• In cheat mode you can use CTRL-B to pull up a list of all NPCs with details about their locations. Cheat mode will stamp your character, but it can be used as a last resort to see if a quest-required boss has gone all-out missing or not.

• If an NPC goes outside the map borders or into the middle of a wall (and it isn't a ghost), BGA will notify you and allow you to relocate the offender to a random free tile somewhere else on the level so that you can reach it. The NPC will not be placed into a vault, but it may be in a secluded room you have to dig to reach. Some levels have rooms behind undiggable walls that aren't marked as vaults. At this point, there isn't much that can be done about those locations beyond using a teleport of some sort.

• If a summons is temporarily removed from the level via Time Skip, it remains in your party. If you leave the level before the summons returns, the connection to the summons is severed and it becomes a not-there party member. If you return to the previous level, the original summons will come back out of Time Skip, but it will now be a separate entity from the one that's in your party. The one on the level will sit there and then decay. The one in your party will not decay and will take up a summons slot from that point on, but will not be on any level you visit. BGA will remove the summons in the party slot if the connection is broken, clearing it for future summons.

• If an NPC spawns and is then killed in the same turn, it can sit on that tile 'dead'. If a creature—including yourself—walks over that tile, a clone will be made, possibly creating an impassable roadblock. Hitting CTRL-C will cycle through all tiles on the level and remove any clones it finds.

• Some rooms will spawn a large group of NPCs. If there are more NPCs than tiles, they will exist 'out of phase'. You can't see or target them and can walk through them as if they didn't exist, but party members may attack the tile they are on. If the NPC has an AOE effect on them, such as an Empire Wight's lighting, it may strike you. You may also hear any sounds associated with the NPC. BGA will 'rephase' the NPC once the square they are on is unoccupied. If the tile and NPC are in sight, you will get the message, '[Name] steps out from hiding.' This may result in an unexpected enemy or two showing up in packed rooms once available space is made.

• Log will flush after special actions are taken so that cut/paste is available immediately.

• Checks for invalid Dark Fey Clones (StarKeep's Faerie Race addon)

+ Bugfix: Limmir disappearing immediately after quest completion. Removed check for 'mod.class.PartyMember' on non party members.

• v2.2.2 - Compatible with ToME 1.1.5 to 1.2.2

• This addon cannot be used to cheat and will not reveal any details about NPCs under normal play circumstances. If an NPC needs to be relocated, you will be presented with its current location and why the addon determined that there was a problem, but the new location is not revealed.***

Power comes at a price, but the price is worth paying...

This addon adds more Taints to the game.

Taints are Inscriptions powered by corrupt forces. As such, they are arcane so Oozemancers and other Zigur Zealots need not apply.
They do not get egos for scaling, instead they scale on a new stat called Taintmarks.
Taintmarks are a measure of how tainted by corrupted forces you are.
Each Taintmark increases the power and duration of Taints by 20%, but decrease you luck by 1 and increase the cooldown on nature gifts by 1.
Taintmarks are gained in many ways:
Each inscribed Taint grants a Taintmark.
Possessing a corrupt power source like Vim or Hate grants a Taintmark.
Being Undead, becoming Undead or changing your shape grants a Taintmark.
Giving in to your Hate grants a Taintmark.
Having Dark Ritual, Ruin or Blurred Mortality grant a Taintmark.
Having Blighted Summoning, Corrupted Shell, Bloodspring or Legacy of the Naloren grant a Taintmark.

Taintmarks are listed on your character sheet under stats.

Current Taints are only a little more rare than normal inscriptions. In v1 they will be much rarer but certain bosses will have a guaranteed Taint drop.

List of Taints:
Devourer: As before but also eats on of your own sustains for more healing.
Telepathy: As before but both effects have the same duration.
Darkness: Darkens the area, grants a temporary stealth boost and makes you activate stealth mode (even if you don't have it), but decreases your darkness resistance.
Vampire: Adds Life Leech chance and amount, but decreases your light resistance.
Blood Magic: Increases your Spellpower and lets you cast with life instead of mana/vim when needed, but decreases your physical save.
Reaper: Increases you physical power and restores resources on kills, but decreases your spell save.
Inversion: Grants damage affinity all, but changes some of your damage to healing.
Shade: Allows you to walk through walls and grants evasion, but reduces your healing.
Ghoulish Rot: Your hits apply Ghoulish Rot disease but your movement speed is decreased. Also blocks hits from being above a certain amount.
Banshee: Scream doing mind damage and causing confusion in nearby enemies, but silences you.
Bone Thorns: Sharp thorns sprout from your bones causing heavy bleeding damage to enemy attackers, but also causes you to bleed. Also increases armour and hardiness.
Blood Snare: Hurl a blood bomb at the target where it explodes, doing blight damage and pinning enemies. This blood bomb is made from your own blood.
Acceleration: Reduces cooldowns, but then they are on cooldown for longer when used.
Exchange: Removes debuffs from you then inflicts you with another random debuff.

Version 3.0: Compatible with ToME 1.5.0

This addon supports game play for character levels higher than 50, primarily for the infinite dungeon (I.D.). This implements a number of subtle changes, rescaling game mechanics and balance for character levels above 50 in the Maj'Eyal, Infinite, and Arena campaigns for ToME. The intent is to make it possible (though certainly not easy) to reach level 500 of the Infinite Dungeon. This is not a nerf or a buff to game difficulty per se, but, rather, an extension of the well-balanced game play from the Maj'Eyal campaign to higher levels.

Some talents and status effects have been adjusted to accommodate the higher character levels possible. You can see a summary of these by checking the "Infinite500" tab in Game Options.

Once a character enters the I.D., the level 50 cap is removed and normal stats-per-level progression is enabled from level 51 onward. The limit on how high primary stats may be trained is removed (limited by character level as normal) and dependent computed value limits are also appropriately increased. No additional Prodigies are gained automatically after level 50. (Note that additional category points and (rarely) Prodigies can be gained by completing I.D. challenges.) Talent mastery levels can be improved more than once, and talent levels are unlearnable as normal in the I.D.

NPC levels in the I.D. have been adjusted to be compatible with higher game difficulty settings.

Most monsters and bosses from the Maj'Eyal campaign are imported into the I.D. along with their respective unique drops.

Traps have been added back to the I.D.

Isolated shops can appear randomly in the I.D. There is guaranteed to be at least one shop on level 1, and they become more common for the first few levels, and then more rare with depth.

Random escorts may be randomly generated on each level in the I.D. unless a challenge has been started, until the normal number (9) have been attempted.

The lichform quest is completed in the I.D. with a new random drop instead of automatically being completed at the appropriate step. There is a new greater vault in the I.D. that affects this quest.

The Corruption/Hexes tree can be learned from a new random drop.

Most major events from the Maj'Eyal campaign are enabled in the I.D., and there is a new event that can award the cursed-aura tree.

Undead characters starting in the I.D. begin with an artefact cloak. This is similar to the Cloak of Deception, but its stats scale with character level and it can spawn randomly for other characters.

This addon incorporates some modified game mechanics:
The ability to shrug off critical hits has been changed. Instead of using the percent value to ignore crits completely, it reduces the crit multiplier by the same amount to a minimum of 100%.

Modified checkHit and checkHitOld functions are employed that allow for wider level differences between opponents (see http://forums.te4.org/viewtopic.php?f=36&t=35229).
Saving throws have been modified slightly to make them more effective at reducing the duration of status effects you fail to save against. (See http://forums.te4.org/viewtopic.php?f=36&t=36715 for details.)

Things planned for the future: scaling of world artefacts with character level, map effects with dungeon level.
