Wip add-on, everything works as of now but I want to re-write some of the code and rebalance it. Always open for feedback!

Changelog

1.0.0 - Release

Adds the undead abomination race. This edition changes the global speed penalty to a heftier movement speed penalty, and fixes crashes from yank out talents.

Minor fix for the racial evolution of Dread.
Now you can become it after the evolution of the lich.
This is done in order to be able to implement the scheme: Lich - Shadow - Dread.

This is an addon that requires the Embers of Rage DLC, it buffs the Whitehoof racial talents in several ways, here is a list of all the changes made:

Increases the death momentum charges gained by leveling "Whitehooves" from 1 - 5 to 3 - 7
Increases the Strength/Magic gained by leveling "Whitehooves" from 2 - 10 to 3 - 14
Increases the flat damage reduction of "Dead Hide" from 1 - 5 to 3 - 6, in addition to now scaling with Strength for even more damage reduction
Gives "Dead Hide" a passive 20% - 80% pin resistance
Lowers the cooldown of "Lifeless Rush" from 52 - 21 to a flat 25, as well as increase it's duration from 3 - 10 to 5 - 11
Lowers the cooldown of "Essence Drain" from 49 - 33 to 40 - 28

Should work perfectly fine with addons that make Whitehoof playable in the main campaign too.

Solves an incompatibility between those two addons :
Eoland's Vampire Race : https://te4.org/games/addons/tome/eolandvampire
Inferno Race Pack : https://te4.org/games/addons/tome/infernoracepack

The two vampire races can now be selected separately.
Eoland's is Undead/vampire, Inferno's is Vampire/Vampire.

This is my own spin on a vampire race. It has some large benefits but also some very strong drawbacks.

Adds the Zilquish race, an artificial lifeform created by necromancers based on the accidental birth of the first skeletal ooze. They're tough, and can use natural talents. Comes with one secret unlockable feature, and one less secret unlockable feature! They will be added to the racepack on its next update, but for now here they are alone.

This addon is now DEPRECATED and might cause bugs. Instead, please use the Inferno Race Pack!

This is a compilation of my undead race addons. This will always be the most up-to-date version.
Banshee
Silence and confuse enemies.
Drift through walls.
Cut away healing.
Banshees begin in a small starting zone of their own.
Banshees are unlocked if you have unlocked any other undead.

Mummy
Embalming increases Strength and Willpower
Entangle wraps up an enemy, slowing them, with a low cooldown.
Inevitability wears away at the resistances of your enemies as your own resistances mount.
Uniquely, they have a small secondary racial tree that removes detrimental effects.
Mummies begin in their own starter zone, a low-level dungeon reminiscent of both the Blighted Scar and the Elven Ruins.
Mummies are initially locked, and unlock by defeating the Mummy Lord

Wight
Blast enemies with elemental power.
Ignore attacks with your ghostly nature.
Unerringly seek out enemies, even behind walls
Wights begin in a tiny starting zone of their own.
Wights are unlocked by completing the ancient battleground event.

And adds a new prodigy for any undead: Dreadmaster

Chinese translation by gooder1029

Adds several new classes and races:
- Bladebender class: Psionic melee fighter that triple-wields daggers and has "meta" talents that can modify other talents.
- Harbinger class: Wilder melee fighter that channels storms through their attacks. More powerful against groups of foes than against single targets. Their class talents do not use resources.
- The Cooler Anorithil class: Revamp of the Anorithil class that must directly alternate between Solar and Lunar talents instead of managing positive/negative energy.
- Zephyr class: Basically a ranged and exclusively lightning-based version of Arcane Blade. Overpowered, not a serious class, and mostly exists to demonstrate instant projectiles.

- Moon Fox race: Race that can radically transform class and generic talents by attaching tails to them.
- Dreamelf race: Overpowered race that can reposition enemies and shorten talent cooldowns.
- Lich race: Undead race that can convert a portion of all their damage into a damage type of their choice.

This addon also makes a couple other changes to make the Zephyr class work:
- Feather Wind is no longer snapshottable, provides less defense but provides both melee and ranged defense, and its maximum encumbrance is no longer spellpower-dependent.

Other than that, the addon tries not to affect existing classes/races/talents. The new classes won't appear on enemies or Adventurers.

You may freely modify and redistribute this addon and its contents, except where otherwise indicated in the Credits section below.

- Changed some talents to mitigate ToME's crit tracking bug ( http://forums.te4.org/viewtopic.php?f=42&t=51477 ). Talents with non-damaging effects that crit (e.g. Countershock, Solar Shield) now try to preserve previous crit state; other affected talents are detailed individually below.
