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.

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.

Allows characters to respec anywhere in game, not just in towns. This is a direct reversion of the change made in 1.2.3 to the way it was in 1.2.2 and before.

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.

• What game options does ZOmnibus provide to configure its behavior? (updated for v16)

Archery dosent get enough love. Give it some with a stealthy afflicted that shoots xor stabs stuff!

Adds in a new Undead race, Ghost. Ghosts have a life rating lower than that of yeeks, but ghosts make up for this by sharing damage with their mana pool.
Being a ghost gives them access to certain categories, Ghosts can gain the following categories; Aegis, Cursed-Aura, Gloom, and Fears.

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.

Dread Knight. More tactically focused than Cursed. Think Gabranth from FFXII meets Hannibal of Carthage.

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).

Primary Features:
Two new Archmage style classes; Arcanist and Elementist.
One new Enchanter class.
Some extra talents for Alchemist.
Lots of new artifacts.
Artifact gems are more interesting to attach to golems.
Crystal Focus/Heart items can be deconstructed to recover the gem.
Angolwen Academy: Get training in the Arcane here.
3 new runes.
Two new item types with unique egos: Ritual Blades and Wardstones.

Arcanist Features:
Like Archmage, but also starts with temporal, meta and nightfall unlocked, and no elemental categories.
Has two unique categories; High magic and Void magic.
Can also unlock Illusion, Distortion, Power and Morph.

Elementist Features:
Like Archmage, but only elemental categories.
Has three unique categories; Elementalism, Corrupted Elements and Elemental Fusion.

Enchanter Features:
Apply a variety of enchantments to your equipment.
Dabble in safe and unsafe hedge magic.
Defeat monsters with your prowess with a staff.

Archmage Features:
1 new category containing 8 arcane/elemental combo spells.

Alchemist Features:
Altered Alchemists Guild quest.
Two new unique categories: Poison Alchemy and Metal Alchemy.
They also get access to Mana Alchemy and Herbalism.

Adds the Mage Knight metaclass, and its six sub-classes.

Forum discussion thread: http://forums.te4.org/viewtopic.php?f=50&t=48329

Phoenix Knight: Powerful warriors who blast their foes with solar fire while calling healing light upon their allies. Their solar fire attacks will strike as either fire or light damage, whichever will hit their target the hardest, and their potent healing and cleansing abilities make them tough opponents to bring down.

Mind Knight: Psionic warriors who strengthen their mental abilities by tapping into their inner magic. Adept at telekinesis, telepathy, and teleportation, they are mobile scouts who can quickly get a lay of the land and sow chaos among their foes with physical and mental debilitations, or even outright compulsions.

Storm Knight: Swift skirmishers who rely on extreme mobility and powerful lightning magic to strike their foes down and avoid reprisals. Extremely fast and difficult to pin down, they can cast entire enemy units into disarray with their wealth of area attacks. All mage knights can cast while they fight, but experienced storm knights are also able to fight while they move.

Earth Knight: The heaviest of infantry, earth knights hammer their foes with physical and natural forces while shielding themselves with the power of the earth. Highly resilient in the face of any attack, earth knights provide a slow and steady offense supported by powerful gemstone shields and the endurance of a living mountain.

Sea Knight: Healers first, fighters second, battle mages a somewhat distant third, while sea knights lack the raw offensive power of other mage knights, they make up for it with amazing personal defense and recovery abilities. And though their attacks may be individually weak, like the sea itself, they are able to wear down even the strongest defenses eventually, eroding their opponents away with gradually strengthening spells, making them terrors in a battle of attrition.

Mana Knight: Experimenting pioneers who do amazing things with raw magical energy. They have the most conventional magical training of the mage knights, even if they sometimes put it to unconventional use. Their arcane attacks can overwhelm the powers of other spellcasters, and while they lack the scope of power of full-fledged archmages, they are masters of the fundamentals of the various arcane schools.

Contains a new hybrid class, combination of wilder and defiler that focuses on debuffs. Note:Equilibrium is increased by 5x the amount of Vim used.

Flavour is you have been cursed by nature's hate at those who harm it.
Can be played with conventional weapons or dual mindstars, stealthy or heavy.
Uses both Hate and Equilibrium.

Summoner:
A full rework is available.
