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.

Adds Trolls as a player race(two subraces), reworks NPCs a bit.

This pack compiles several classes, with an emphasis on hybrid design. Not all classes are complete: the ones which I'm not satisfied with are marked as either INCOMPLETE or "in BETA".

The classes included in this pack are:
- The Transcendent Fist is an unarmed Psionic warrior, using a gem in his TK slot to hit with flexible energy types.
- The Storm Warden is a melee-and-ranged skirmisher with magical mobility and support spells.
- The Striker is a cunning and covert class, with a focus on delivering shock-and-awe thunderbolts from stealth.
- The Gravitic Infantry is a melee-focused Chronomancy user (formerly named the Heavy).
- The Creep is a stalker in the dark, cunning and covert in his hate.
- The Vector uses disease and debilitation to keep his foes at range while he snipes them to death.
- The Flenser is a Defiler whose knives debilitate and torture his victims.
- The Blood Mage is a Vim-based caster with a mild dip into staff-melee combat.
- ... and more!

(BETA) Shield Hero is an Adventurer who starts with heavy armor and a shield. Not very exciting unless you were annoyed about not being able to equip your Adventurer's shield right away.
(BETA) Prototype Hero is an Adventurer who starts with 1.3 mastery in every category. Not very useful for players, but it might be interesting for addon writers to spitball new category combinations.

(INCOMPLETE) The Flux Marauder is a Paradox thug, stealing time from his enemies.

x (Removed): The human-only Embers of Gerlyk are fire-using magical martial artists. Removed pending new content / 1.6 features.
x (Removed): The skeleton-only Fossils are geomantic martial artists. Removed pending new content / 1.6 features.

"Weeks ago, you arrived into the Shertul Fortress, following the collapse of Nur right behind you.
You were able to save a small group of villagers, who have set up a town in the north end of the Fortress.

Weeks later, as the town is coming together, you hear a loud growling sound coming from the south.
As you head to explore it, you find a weakened horror.
Right before you engage the beast however, you see what appears to be a... portal, directly behind it.
The beast appears to have come from it... meaning there are more monstrosities out there...

Alongside the only possibilty of escaping from this place...

Steeling your resolve, you have choosen to explore the portal, and look for a way out."

---

In this addon, you attempt to complete the farportal as many times as possible.
In order to help this, a couple of things have been changed.

You are given access to a town in the north.
You gain the same basic sorting storage as in the main game, and the training dummies have been moved to the south.

In the Town, you can find a multitude of shops, and a Merchant.
The Merchant is capable of doing many things to aid you on your way.

He can craft you tier 1-5 artifacts, for fair(or so he says) prices, to offer you a boost when you find yourself struggling.
If you don't like the item you got, you can pay him 10% of the original cost to reroll it again!
He can also craft you companions, if you ever find yourself struggling. (These guys will not level up however, so don't think about stacking em. :wink: )
You can also give him 33% of your gold to restock all shops.

Lastly, and most dangerously, you can ask him to break 'Seals' of the Farportal, which will directly summon Farportal Bosses into the fortress.
You can choose between 1 to 10 at once. (6+ are slightly buggy atm, so be advised)
This is expensive, however, and will cost you, at the least, 2000 gold in your pocket.

Additionally, you gain 10% of your current gold every time you complete a farportal, alongside an experience boost.
This boost will decay over levels, but is noticeable for some time.
The gold bonus will reward players who dare to attempt the Farportal without maximizing their gold spending.

Dive into the Infinite Farportal, and pray, or you will never again see the light of day.

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.
