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.

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 Lost City of Vulcus

Some events in history are of such importance and have such wide ranging ramifications that they become fixed points -- junctions in time that must and will happen in order to maintain the integrity of the chronoverse.

Lost ages ago, Vulcus was considered by many to be the greatest center of Dwarven learning below the surface. Even up until the fall of Reknor in recent times, however, Dwarven innovation and breakthroughs continued, seemingly by miracle. Fate, however, dictates that one of the greatest untold secrets of the Empire cannot remain hidden forever. Perhaps you will be chosen to take part in this crucial point in history -- to reap the rewards or to suffer the consequences.

This addon incorporates a new major event (like the drake cave or fearscape invasion portal) that has a chance to occur (possibly more than once) on each level in various zones (Infinite Dungeon, Spellblaze Scar, Ardhungol, High Peak, Reknor, Shadow Crypt). Within the game, this event is most like a combination of the Lost Merchant and Limmir quests, and is intended to replace those for characters in the I.D.

Recommended level 10+ (depending on class). The intended difficulty is slightly higher than the Limmir quest, and there are gradations of success. Participating in the event when it spawns is completely optional and you can do it later if desired.

This is possibly the most complex encounter in ToME, with a large number of NPCs, enhanced AI, and various terrain effects. It is compute heavy and will tax slower computers (even with reduced graphics settings).

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.

This addon adjusts the way friendly NPC's react to hostile actions by the player.

In most cases, the personal reaction of an NPC to the player (friendly/neutral/hostile) will slowly recover (by 10% each turn, minimum 1 point) back to it's default value over time. If the player doesn't further aggravate the NPC, it will eventually become neutral/friendly again. (Though it will still probably have the player targeted, depending on its ai settings which are not addressed in this addon.) The exception is if the player kills another friendly NPC within LOS, which will result in the NPC becoming permanently hostile to the player in most cases.

Putting a detrimental status effect on the NPC will create a -25 (negative) reaction to the player (in addition to the penalties from any damage caused).

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!
