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.

Adds the Commando warrior class to ToME. Uses a combination of archery, grappling, and stealth techniques.

A lifetime of training in archery, hand-to-hand combat, and stealth
has given rise to the Commando, a warrior of unparalleled cunning and tenacity.
Fighting tactically, they pick off key targets from hiding with their bow before
moving in and announcing their presence to demoralize the survivors.
Whatever remains is swiftly put down with a combination of grappling techniques and weapon strikes.

Adds in a new Undead race, Ghost. Ghosts have a life rating lower than that of yeeks, but ghosts make up for this by sharing damage with their mana pool.
Being a ghost gives them access to certain categories, Ghosts can gain the following categories; Aegis, Cursed-Aura, Gloom, and Fears.

Original Class idea and design by Faeryan

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!

Quality of Life improvements for resting and auto-exploring.

v3.5.0 *** FOR ToME v1.6.5 ***
This is a fork (with permission) of Marson's auto-explore and rest tweaks. It includes as well C.Lowe/CaptainTrip's improvements as well. It does not include, but recommends also using Johnny0's Faster RRE add-on for even better rest and auto-explore experience. This add-on contains numerous Quality of Life improvements designed to make resting and auto-exploring easier to use, brings the add-on overall up to being compatible with 1.6.x, and generally seeks to remove it being more optimal to do timed rests or manual recovery (particularly to help higher difficulty level and players without Faster RRE). Cleaned up feature list in this take, to make it easier to see what it does.

It is recommended to turn off Marson's Rest and Auto-Explore as well as C.Lowe's Rest Tweaks if using. This addon is meant to include all of them.

Latest Update Notes:
• Changed steam sustain behavior to match current gameplay. Before sustains tended to shut off when available resource was 0, now they don't seem to do so. This will now only turn off sustains that drain steam if steam is going below 0, so as to get to a steady finish state.
• Fix minor bug where stealth enabling was always on if you had it.
• Added new option to ignore quest members when resting or exploring. It defaults to off but for those folks that know they want to ignore those quest allies and rest a bit.

Existing Features:
• removed First Sighting and Reset on Rest. Someone can patch them in if they'd like it back, but I'm not really keeping them alive.
• Fixed actor bugs causing Elemental Surge to never reset. Thanks Reca♥den.
• Fixed bug with Paradox Spacetime Tuning from 1.5.5. This may rebreak posessors with paradox, hard to kinda test.
• Mostly verified working on 1.6.0
• Compatibility with restart sustains. Thanks zizzo.
• When resting, it will check for infusions and runes that could be used to accelerate HP, Mana, or Equilibrium (via Ancestral Life or Meditation) recovery. If the acceleration appears significant, it will use them, rotating from first available infusion or rune outward. In experiment, I found this often reduced rest turn time by 50-80 percent, improving the more drained the resource was. Particularly helpful for Mana, as it avoids trade-off advantages of short term resting (for increased mana regen) + rune use by just handling that more optimal play for you automatically without breaking rest.
• Support for steam implants, with usual checkboxes. This may not always be faster based on steam sustains that may disable after the initial round of rest and steam implants having very long cooldowns (30+ turns) and steam's resource max being pretty small. It tries to be conservative on that, so will most likely help for cases where your functional steam regen rate is < 2.00 and never activate for things much above it. I found I was often getting 5-20 steam per turn, which makes the implant support useless.
• Supports for medical healing salve injectors. Cooldown measurements are a bit odd here, since they can range from 5-20 depending on injector. Went with 10 as a happy medium for how many turns of natural regen is considered to be equal to the cooldown cost of using it.
• Adding support to auto-stealth if available and not stealthed.
• Option for ignoring small damage when moving and resting, basically if it is <5%, it will ignore it by default, prevent small DoTs from preventing rest.
• Options added to control whether or not to use inscriptions to accelerate recovery of things.
• Fixes a ToME bug that can cause autoexplore or running to move only a single square and hang if used immediately after killing an enemy.
• Lore discovery will only stop autoexplore if it triggers a popup.
• Autoexplore will ignore Exploratory/Infinite Farportal return portals until the entire level has been explored.
• Ignores special terrain features such as Font of Healing after they are first discovered.
• Ignores open chests and alt Maze floor cracks.
• Rest and AE ask for confirmation if you have an escort in your party.
• Ignore already activated pedestals.
• Checks for and waits on any rechargeable items.
• Checks for and reloads any ammo in offhand quiver.
• Waits for cooldowns of talents set to auto-use.
• Waits for depleted air to replenish.
• Combines all checks into a single instance of rest, rather than having cooldowns etc. require a second resting phase.

Determines how auto-explore and running respond to telepathy, including mouse moves. Regardless of the setting, hostiles seen via telepathy will not halt resting or the Rod of Recall, nor trigger automated talents. Unique or powerful monsters (rank > 3) will always trigger a halt to running when they are spotted via telepathy for any mode except 'Original'.

• Compatible with ToME v1.6.0

Notes:

• Telepathy will not prevent auto-exploring the way normal sight will. If a halt is triggered by telepathy, hitting auto-explore again will move you at least one more square in the direction of the auto-explore path. If in 'Always Viligant' mode and a hostile is within telepathic sight (but not normal sight), you will auto-explore in 1 square per keypress increments.

Adds a new game menu option "Show known Landmarks", which presents a list of landmarks (up/down stairs, golden chests, zone entrances and the like) that you've seen on the current level and allows you to go to them or view them on the map.  You can also set your own landmarks for later reference by right-clicking on the map and choosing "Set landmark".

Also available as part of the ZOmnibus Addon Pack and ZOmnibus Lite.

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?

Adds Draconians as playable race, with their own starting area. This addon was updated and forked by Aura of the Dawn, in the absence of ajfluffy.

Second branch, due to upload system differences requring a new shortname.

Adds Beholders as a playable race. Created by ajfluffy (design, code and conception) and rexorcorum (ideas and artwork), this addon is now being maintained by Nagyhal under the guidance of rexorcorum in ajfluffy's absence.

Edit: Had to change the addon's short_name, and so v1.0.6's automatic upload helpfully made us a completely new addon page. Of course it's all on Steam, which is beautiful (thank you DG!), but I'm hoping we can merge the older versions into this thread. We'll look at it tomorrow.

Edit of the edit: In the meantime, players who have fallen afoul of my clumsy Flame Laser bug are encouraged to upgrade to v5.9.2 for compatibility reasons. Have fun and happy facemelting!
