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.

Donators/Buyers bonus!

Adds two races, one class, a new town, and a new low level dungeon. Completing a quest to explore the new dungeon unlocks purchasable perks in the town. This quest is the starting quest for the added races, but anyone can access an alternate version of the quest with the same rewards. Look toward the coast east of Last Hope to get started.

Available perks (cost varies):
Reveal Exotic Weapons Mastery (must already know Combat Training; Combat Training can also be purchased as per Last Hope shops).

Gain the ability to invest in Heavy Armour Training and equip mail(heavy) armor by meeting the requirement with the highest of Constitution and Dexterity (or Strength, as usual).

Gain bonus attack and movement speeds and a chance to evade incoming damage while wearing mail(heavy) armor. These values scale with Dex and Con, respectively.

Learn (locked or unlocked) a new Psionic/Mindstar combat talent tree. Similar to Wild-Gift/Mindstar mastery, this tree also has a Psiblades sustain. Once learned, you can also pay to boost mastery (as with Mindstar mastery from Zigur).

---

Psionic/Mindstar combat:

Psiblades:
Increases damage and physical power when attacking with Mindstars. When sustained, increases the damage modifiers and mind stats granted by equipped mindstars (this is an exact copy of the wild-gift/mindstar mastery psiblades talent).

Mind Thorns:
Instantly touch the mind of an adjacent foe, creating mental thorns which reduce mind save and deal mind damage each turn for a few turns.

Mind Storm:
Create a storm of psionic energy which lasts for a few turns. The storm will overheat the mind of foes in the area, causing them to burn (stacking). Allies in the area will be obscured by illusions, reducing the bonus damage of critical hits dealt to them.

Psionic Balance:
Attack an adjacent enemy with your mainhand Psiblade and channel the energy through your offhand to create a psionic damage shield around an ally or yourself. The power of the shield is based on the damage of the attack and can be a mental critical. The shielded target will also regain an amount of Psi based on the damage of the attack.

This addon grew out of an attempt to rework the Arcane Blade base class from the TOME module way back in beta. Previous versions can be found under the "Arcane Blade Rework" addon. I got sufficient positive feedback, and it was a sufficient departure from the original class, that it was decided to split it off to its own class, while letting the Arcane Blade be updated by others.

The class revolves around melee spells, utilizing a mixture of stamina and mana require skills. Probably the most unique feature are the elemental stances, only which one of is active at a time, and which are activated by using the basic elemental strikes.
