This is a compilation of my undead race addons. This will always be the most up-to-date version.

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

There are other wight addons:

• https://te4.org/games/addons/tome/wights
• https://te4.org/games/addons/tome/highwightrace

But they weren't quite what I was looking for.

Please report any problems or comments in the forum thread below.

Fallen has been added to the base game as an evolution for Sun Paladins

This addon contains the original version, a base class afflicted/celestial hybrid.

Fallen are unlocked alongside Sun Paladins.
If you want to skip straight to it, I recommend using: https://te4.org/games/addons/tome/ignore-raceclass-locks

Please report any bugs on the forum thread.

This class is originally inspired by the enemies John and Aluin, Afflicted Sun Paladins.

Fallen have a mix of old and new trees.
Enemies do not generate with Fallen talents.

Celestial Combat
Shadows
Gloom (locked, level 0)
Bloodstained: By making bloody attacks, increase your positive energy.
Darkside: Consume positive energy for attacks and mobility.
Shadows of Suffering (locked, level 10): Use your shadows for defense and control.
Crimson Templar (locked, level 10): Magical abilities that manipulate bleeding and the battlefield.
Black Sun (locked, level 10): Celestial attacks using gravity.

Celestial Light
Cursed Aura
Self-Hatred: Spend life for Hate and power.
Dirges: Useful songs in the style of Chants and Hymns.

Adds Banshees as a new type of undead that harrow enemies with their sorrowful voices.

Changes Paradox to hopefully make things flow and scale better.

• Paradox never causes talent failure - It either casts the talent or casts both the talent and an anomaly.
• Paradox costs increase more at high paradox - they scale with excess paradox rather than with the square root of excess paradox.
• Paradox scales your Magic stat rather than your Effective Spellpower for paradox spellpower calculations.

The main limit on using chronomancy is your ability to handle the risk of the anomalies.

A variation on wyrmics, as a multi-elemental debuff-centered class.
Rather than having their abilities scattered among the elements, they'll rank up melee attacks, mental attacks, and elements separately.

The core of Wyrmic is:
Combat Techniques
Draconic Combat - provides weapon attacks.
Draconic Energy - provides mindpower attacks.
Draconic Body - provides mobility and survivability.

Then, a wyrmic picks one of the six natural elements: Fire, Ice, Lightning, Sand, Acid, or Poison. Each element has a single ability available right away, and a set of advanced skills that require a category point to access.
Finally, the advanced Prismatic Tree rewards you for changing elements.

Apex Predator - new generic tree that fills in a few gaps and lets you wear gems.
Please leave feedback and bug reports in the linked Forum Discussion thread.

Compatibility
Will be incompatible with other Wyrmic replacements.
Incompatible with some addons that change gems, especially Alchemist reworks.

Other
Acid and Venom have been separated into two different aspects.
This addon does not let you turn into a dragon.
This addon does not let you summon dragons to help you.

A new class, a Celestial summoner who draws on the powers of Shandral's other planets to call up elementals.
Their basic trees summon and support Fire, Ice, and Lightning Elementals, as well as providing utility effects.
Their unlockable advanced trees rain down Meteors and twist Time Elementals into being.
They start with Chants, and a new tree in the vein of chants and hymns. They can unlock Celestial Light.

Their main resource is negative energy, which they generate by summoning and some other spells, and spent by others.

This mod should be compatible with just about everything.
Superloads

• data/talents/uber/mag to support Blighted Summoning
• mod/class/interface/combat.lua to support Glacial Path's speed boost.
