This addon adds crossbows! Crossbows are simple weapons that anyone strong enough to carry them can use.

The crossbows use bolts, and although they fire slower than bows, and dont scale nearly as much with stats, in addition to not having related skills, they pack quite the big punch, and have a large chance of critting. However, they also have a very limited ammo capacity, making them unsuited for sustained use.

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 some additional entries to the inventory's use-item dialog to more conveniently apply some talents to items in inventory.  Current added entries are:

• "Extract gem", to apply Extract Gems to a metal weapon or armor
• "Convert to alchemist gems", to apply Create Alchemist Gems to a gem
• "Extract energy from gem", to apply Matter is Energy to a gem.
• "Grasp telekinetically", to apply Telekinetic Grasp to a weapon or gem
• "Use as sentry", to apply Cursed Sentry to a weapon

In addition, if you have turned off the "Object & Creature links" chat message filter under Game Options, the "Link item in chat" entry is removed from the dialog.

(new in v3) Also adds game option "[ZOmnibus] | Allow object actions in stores", which will allow some item actions (like tagging) to be performed on items in your inventory from within the store dialog.

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

Adds several new gem types and attempts to fill in some gaps in Tiered gem colors; also adds the Crystal race.

This is a continuation of jayseesee's original addon. It's my hope that the gems in this release are balanced, consistent across tiers, and useful to a variety of different characters.

Also hopefully all the Crystal's balance issues have been worked out: it should be an interesting tactical challenge to make best use of its unique mobility, find the right time to exploit its Runic Saturation status clear Stasis talent, and optimal self-imbued gemstone for each dungeon.

As always, please let me know if you find any issues in terms of bugs, game mechanics, or interface!

This pack compiles several classes, with an emphasis on hybrid design. Not all classes are complete: the ones which I'm not satisfied with are marked as either INCOMPLETE or "in BETA".

The classes included in this pack are:
- The Transcendent Fist is an unarmed Psionic warrior, using a gem in his TK slot to hit with flexible energy types.
- The Storm Warden is a melee-and-ranged skirmisher with magical mobility and support spells.
- The Striker is a cunning and covert class, with a focus on delivering shock-and-awe thunderbolts from stealth.
- The Gravitic Infantry is a melee-focused Chronomancy user (formerly named the Heavy).
- The Creep is a stalker in the dark, cunning and covert in his hate.
- The Vector uses disease and debilitation to keep his foes at range while he snipes them to death.
- The Flenser is a Defiler whose knives debilitate and torture his victims.
- The Blood Mage is a Vim-based caster with a mild dip into staff-melee combat.
- ... and more!

(BETA) Shield Hero is an Adventurer who starts with heavy armor and a shield. Not very exciting unless you were annoyed about not being able to equip your Adventurer's shield right away.
(BETA) Prototype Hero is an Adventurer who starts with 1.3 mastery in every category. Not very useful for players, but it might be interesting for addon writers to spitball new category combinations.

(INCOMPLETE) The Flux Marauder is a Paradox thug, stealing time from his enemies.

x (Removed): The human-only Embers of Gerlyk are fire-using magical martial artists. Removed pending new content / 1.6 features.
x (Removed): The skeleton-only Fossils are geomantic martial artists. Removed pending new content / 1.6 features.

Incompatibilities: There shouldn't be, unless you name your class "Hero" also.

Adds Trolls as a player race(two subraces), reworks NPCs a bit.

Makes the actor healthbars a 3/4 height vertical bar in the lower left, receding upwards with damage so less vital information is lost behind perspective wall tiles. Designed for use with my corner-only threat borders, but also looks passable with the default four-corner design as I also made the bar render on top of the frame. (Only issue is that full health gets lost against the ally-color frame). Looks good in sizes down to 32x32, fails to render in 16x16 presently. Intended for Shockbolt tiles and frames, not much use with roguelike.

This addon updates the Berserker class in an effort to make its early game
more interesting by replacing some of the more generic abiliities with access to the
Bloodthirst set from level 1, along with a small redesign of a few key abilities

This addon is home to bonus races, objects, and even a custom zone, for all your turtle pleasures.

Races;
Turtle - The normal, all around tanky subrace. Destroy your foes with potent damage reflection and regenerative properties.
MegaTurtle - Imagine normal Turtle, turned up to 11.
EarthTurtle - Potent damage reduction and save powers. The purely defensive focused Turtle.
IceTurtle - Melee's nightmare, fights with constant damage shields, ice blocks, and cold damage reflection.
VolcanicTurtle - Incredible aoe potency. The purely melee focused Turtle.

Objects;
Tauntlets - Gauntlets with the power to block.
A multitude of varied Artifacts.

Zones;
The Turtlemire - Home to all Turtles, face off against all 5 Turtle subraces.
Ancient Turtle Cave - Home to the great Turtle Demigod Rex, make your way through 3 powerful Bosses, Rex himself, and claim your rewards.

Enemies;
All subraces can be found in the game as npc opponents.

Changes the floating text to a different font

A simple addon that adds a few items to your starting Inventory as an Adventurer:

An Iron Shield.
An Iron Greatsword.
A random tier 1 gem.
A pair of Rough Leather Gloves.

If you have Peppersauce's Misc Objects Addon installed, you will also get:

2 Whips.
A Rapier.
A Shortstaff.

It will, however, work without it.

You will, also, acquire a flat bonus of 25 to your encumbrance.
This is to stop yourself from being encumbered at the start.

Adds a game option "Alternate zones" to enable or disable (or optionally force) v1.0.3's new alternate zones, either globally or individually by zone.

Also available as part of the ZOmnibus Addon Pack.

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?

Double sided weapons are held with both hands, doing 100% str damage and having some dex requirement, with the ability to perform an extra offhand each attack.

These weapons are considered two-handed weapons and also can be used with skills that requires and offhand weapon.

The chance to perform an offhand attack is 20%, but can be increased with proper training.

Gives you a chance of dodging your own arrows or sling shots based on your Danger Sense talent level. Useful for archery-using characters (other than Archers, who are already protected by Shoot Down) against monsters that can pull you to themselves and into the path of your own in-transit missile.

"Weeks ago, you arrived into the Shertul Fortress, following the collapse of Nur right behind you.
You were able to save a small group of villagers, who have set up a town in the north end of the Fortress.

Weeks later, as the town is coming together, you hear a loud growling sound coming from the south.
As you head to explore it, you find a weakened horror.
Right before you engage the beast however, you see what appears to be a... portal, directly behind it.
The beast appears to have come from it... meaning there are more monstrosities out there...

Alongside the only possibilty of escaping from this place...

Steeling your resolve, you have choosen to explore the portal, and look for a way out."

---

In this addon, you attempt to complete the farportal as many times as possible.
In order to help this, a couple of things have been changed.

You are given access to a town in the north.
You gain the same basic sorting storage as in the main game, and the training dummies have been moved to the south.

In the Town, you can find a multitude of shops, and a Merchant.
The Merchant is capable of doing many things to aid you on your way.

He can craft you tier 1-5 artifacts, for fair(or so he says) prices, to offer you a boost when you find yourself struggling.
If you don't like the item you got, you can pay him 10% of the original cost to reroll it again!
He can also craft you companions, if you ever find yourself struggling. (These guys will not level up however, so don't think about stacking em. :wink: )
You can also give him 33% of your gold to restock all shops.

Lastly, and most dangerously, you can ask him to break 'Seals' of the Farportal, which will directly summon Farportal Bosses into the fortress.
You can choose between 1 to 10 at once. (6+ are slightly buggy atm, so be advised)
This is expensive, however, and will cost you, at the least, 2000 gold in your pocket.

Additionally, you gain 10% of your current gold every time you complete a farportal, alongside an experience boost.
This boost will decay over levels, but is noticeable for some time.
The gold bonus will reward players who dare to attempt the Farportal without maximizing their gold spending.

Dive into the Infinite Farportal, and pray, or you will never again see the light of day.

The Higher were not the Conclave's first attempt at infusing humans with magic, but rather the result of long years of failed creations. The descendants of those who managed to survive these experiments are today called the Fallen. Although they command intense magical power, their bodies are weak and sickly.

Although short staves only take one hand to use, they cannot be dual-wielded in 1.0.5. This was mentioned in the forums, and has been fixed for 1.0.6. But I reaaaally want to play a dual staff reaver and I'm impatient, so boom. Addon.

This is exactly how staves will work (barring future changes) in 1.0.6. I "borrowed" the code from the ToME git. Probably not compatible with any other staff-related addons, sorry. I'm lazy and use overload functions. Also, friggin' delete it when 1.0.6 comes out.

Contains a new melee class - the Blood Knight

Details & discussion here:
http://forums.te4.org/viewtopic.php?f=50&t=40159

Adds two new shadowy Celestial classes.
First is the Moon Paladin, who fight using two weapons and the two moons.
Second is the Starslinger, who imbues their shots with the power of the stars.
Also two new subraces that start in the Far East, regardless of class.
Mardrop Humans and Star Elves.

Now with a new starting zone: Save the Sunwall crops from a worm infestation.
New second starting zone: The Tenebrous Glades.
Travel to the barely made training camp of Midnight via a jumpgate on the west side of the Gates of Morning, then head southwest.
The shadows summoned to conceal the camp have become restless and dangerous. Quiet them down and investigate what is working them up.

Currently there are nine new categories.
Celestial/Night: A utility based generic category that generates negative celestial energies.
Celestial/Lunar Combat: Powerful offensive talents invoking the power of the moons.
Celestial/Guidance: Some defensive and one offensive talents for Moon Paladin.
Celestial/Shooting Stars: Combines star magic with ranged weapons.
Celestial/Deep Space: Some high level celestial magic for Starslinger.
Celestial/Sigils: Shape negative celestial energies into traps.
Celestial/Glory: High level light magic for Sun Paladins and Anorithil.
Celestial/Moon Magic: Magic derived from the two moons of Eyal.
Celestial/Umbra: High level dark magic for Anorithil and Star Slingers.

It also grants Sun and Glyphs to Sun Paladin at 1.3 mastery.
Reworks Chants and Hymns, and buffs Sunburst.

Important: this addon will have no effect if left unconfigured! Please read the description!

Recommended settings:

• Requested FPS: 30
• Resting divider: 10
• Running divider: 5

Description:

Enables faster run/resting by use of FPS dividers.

These dividers simply divide the game's requested FPS by their respective values while resting or running. After starting a new game or loading a saved character, configure this addon by hitting escape -> video options. Setting these dividers to something greater than one can substantially reduce the amount of time required to finish resting/running on older computers.

Just be careful when resting on an escort mission...

Changelog:

See the forum discussion for the changelog.

Adds Wights as playable undead race.

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!

This addon adds in a Faerie, or Fey, race into ToME. This addon was originally created by Kaballah, but he hasn't been online in over a year.
Instead of letting it die (I mean, how could we not be able to play as a Faerie?) I decided to fork it over into a playable form.
I've taken it, modified it's values, and changed it's 4th talent.
You can nab it here.

Dark Faeries are Faeries that have given up much of their natural agility and defense in exchange for bonus offensive potency.
They are extremely frail, even more so than their more agile counterparts, but make up for it with faster offense, higher damage, and many different tricks.
Despite all thoughts otherwise, they are still, mostly, a playful bunch to be around, if not a bit more painful in their method of invitation.

"Shadows are magical creatures created by spellcasters to be used as tools to help them achieve their goals.
Even if they don't have a physical body they still can use mundane objects as they please.
They are resistant to darkness damage but they are vulnerable to strong lights, their bodies will cover any source of light.
They have a strong affinity to negative energy but their body can react to positive energy."

Improves the default sort order of items in the player's inventory.

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

This addon improves rare drops (Salmon colored items) by adding a single level appropriate ego to them. (They use the same methods as normal randarts.)

This should make rare drops more useful on average (generally slightly better than normal egos) though still less powerful than full randarts.

Files affected: mod.class.GameState.lua

Adds additional options to talent auto-use

Removes all the unwanted categories from the level up screen so it runs smoothly.
Has an interface to allow you to select which categories are displayed.
Compatible with other addon categories.

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.
