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.

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?

Stoics are warriors who dedicate their lives to mastering countless secret techniques.
Their wide variety of abilities allows them to fight their way out of any situation.
However, in order to fight at full effectiveness, they must first focus and steel themselves against the battle to come. Exceptionally skilled Stoics are said to infuse their attacks with elemental powers to create radical new fighting styles.

Stoics are a warrior subclass inspired by the Samurai class from Hengband. They are a melee class with a wide variety of specialized combat techniques, but require judicious use of their unique Focus resource to succeed. Their advanced trees allow them to alter the element of their attacks and grant passive effects as long as the stance is maintained.

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.

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.

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.***
