Bite-Sized Update:
Replace some enemies with powerful Randbosses. Enemies of a Unique rank or higher, who are given random class talents.
Every rank of enemies has their own tier of loot.
As you level up, you'll see more of these buggers walking around.

You spawn at level 12, and can level up to a maximum of 200.

Increase your rank as you slay your foes.

You can see your kill counts and your rank experience in the quest log.

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.

Other addons that affect these files might not be compatible.

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.

This adds new weapon types and egos to the game.

- Tridents are unchanged, but generate more often.
- Whips can now generate normally, and their accuracy bonus now slows the target.
- Swordbreakers are weak knives that have a chance to disarm on hit, and give bonuses to dual weapon defense.
- Rapiers are 1h weapons that use dagger mastery and rely on strength, dexterity, and cunning.
- Bucklers are light shields that can greatly increase your defense and give you faster attacks against those who miss you in melee.
- Buckler offense tree at varying levels of access for 5 or so classes. Skirmishers start with a buckler.
- Spears/Greatspears are slow weapons that can attack from a distance.
- Clubs/Greatclubs are maces that can pick up mindstar egos.
- Throwing knives can be used in melee or as a short ranged attack with the shoot talent.
- Daggers will now use the higher of strength or cunning if you don't have Lethality.
- Mindslayers can now equip ranged weapons in their psionic focus slot.
- Aurastones are magic-based items that can be equipped to modify your unarmed attacks.
- Magic Weapon Mastery applies to staves, aurastones, and sceptres, and can be learned in Angolwen.

Most of the stuff here can be individually turned on/off in the Game Options menu. So you could use this addon just for the extra tridents if you really wanted to.

Adds a new race choice (Kobold) which leads to two new subraces.

Kobolds are small humanoid-like people, who inhabit the Thaloren forests and spend their lives among other rarely sighted legendary creatures, like woodland spirits and fairies. Inside the taxonomic family of Kobolds two different genera are known to exist: a common variant, simply called the Kobold, and the much rarer Gremlin. Their most notable feature is a set of supernatural sharp and strong teeth. According to some myths, Kobolds rely on it to feed on metals and gems, which isn't quite accurate however. Still, their poisonous bite is a dreaded weapon and Kobolds commonly fall back on it to defend their life or while hunting for food.

A. The common Kobold:
He is very agile, stealthy and quick. As he grows more experienced, a Kobold develops means to raise his quickness to an extraordinarily magnitude. He disposes over a deadly, poisonous bite and is very resilient to poison himself, granting a resistance bonus of 25% to poisons of all forms. Due to their agility and quickness, Kobolds make very formidable warriors or rogues, that don't have to shy competition with members of the taller races.

Stats:
-3 Strength, +6 Dexterity, +0 Constitution, +0 Magic, +0 Willpower, +2 Cunning, Life per level: 10, Experience penalty: 15%, Immunities: 25% poison

B. The Gremlin:
Gremlins are very emotional by nature and often victims to a sudden change of mood, which can lead to an outburst of extreme aggressive or depressive behaviour. Racial abilities of gremlins are tied to different moods. Experienced gremlins can find ways to control their mood and harness it to gain specific situational advantages, which at the same time, however, are balanced by certain disadvantages. While under the influence of a mood, Gremlins have an affinity to either of the spheres of Light, Darkness, Blight or Nature, and gain certain bonuses and penalties, that are related to their affinity.

Stats:
-3 Strength, +2 Dexterity, +0 Constitution, +2 Magic, +2 Willpower, +2 Cunning, Life per level: 9, Experience penalty: 15%

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.***

Adds the chaotic human subrace, which get a random talent on every levelup.

Also has the following option under Gameplay:

Extra Chaotic: This affects who gets random talents on levelup:
Standard: Only the chaotic race does.
All Races: The player gets the talents regardless of their race.
Enemies Too: Everything gets talents on levelup, even enemies.

Adds in the Intense, Brutal, and Chaos difficulties, stepping stones between the vanilla difficulties, and additionally grants free stat bonuses based on difficulty level.

Let there be Gnomes!

Addon-content:

1. New subrace: Gnomes (included: own starter-zone and quest)

2. Additional zones and quests:
a) Midlevel zone & quest (15-20): starts near Last Hope, related zone has to be found on the worldmap
b) Highlevel zone (35-50): a hidden zone, that can't be entered by normal means / a quest starts inside, on the 2nd level

About Gnomes:

Gnomes are distant relatives of Halflings, albeit a tad smaller in stature and much weaker physique. In the world of Maj_Eyal, not much is known about them for simple reasons: they usually don't leave home to go on adventures, much less to take part in heroic endeavours. People commonly mistake Gnomes for extraordinary small and malformed Halflings, even if that is far from being the truth. The existence of Gnomes as a proper subspecies has passed history unnoticed for centuries, while they lived peacefully, silent and hidden within Halfling society, dedicating their lives to the study of the physical, magical and historical dimensions of Maj'Eyal.

In theory, however, gnomes make great adventurers. While they lack any of those physical attributes, that are commonly associated with a lifestyle dedicated to performing heroic deeds, they got the ability to gain advanced knowledge about almost anything related to skillful adventuring. They start their career with two instead of just one racial talent trees and are able to learn new talent types not available to their choosen class. As a result, they make for very flexible game play, but they are challenged by a low life-rating.

--- Major Revamp as of 20.12.2014 ---

! ! ! ! ! No compatibility with older versions ! ! ! ! !

Gnomes now offer a truly experimental game experience. Gnomes get two racial trees:

- one tree allows them to learn just about any talents associated to different meta themes (they can learn one type each of these groups: technique/cunning, spell/celestial/chronomancy, psionic/wild-gifts, cursed/corruption).

- the other tree provides general offensive and defensive benefits as well as resource (stamina, mana, psi, equilibrium) regeneration.

As a result, playing as a gnome makes it possible to spice up just about any class with new talent combinations normaly only experienced when playing the Adventurer class.

Additonaly, gnomes still start with their Gnomish Pocket Encyclopedia - an item, which at level 30 allows them to pick one further talent type from about just any category (excluding stone wardens talents).

Specifics - Stats and Racial Talents:

Stat modifiers: -4 Strength, +1 Dexterity, -6 Constitution, +1 Magic, +0 Willpower, +6 Cunning, +0 Luck
Life per level: 6
Experience penalty: 10%

Update (24.01.2015):

- added a visual distinction between generic and class trees in the dialogues where you choose which talent-type to learn

Be the mighty green warrior. Defeat your enemies with sword techniques, magic arrows, and a wide variety of new tools and charms.
Requires the Weapons Pack addon.
