This is a stand-alone Quality of Life pack that improves some minor things about ToME gameplay.
This pack adds particles to certain effect types (such as "dizzy stars" for stuns and confusions, or green bubbles for poisons).
Background: It is otherwise difficult to tell if or when certain effects procced or not, and it is also kind of obnoxious having to check each and every enemy for whether they're affected by something or not.

Adds the Dark Priest, a mage subclass.

Even in an age of supposed prosperity, there are many who lose their lives in vain. Those who tend the wounded, returned home from battle or adventure, are highly skilled in the arts of healing, many using arcane techniques. But there are some who have seen too much. They have formed a brotherhood of those who have accepted the Dark Truth. Eyal has but one true God, and He demands sacrifices. The Dark Priest and his brethren tap into arcane energies to deliver the bad word unto all the people of Maj'Eyal. They manipulate darkness and life energy to convey their message of doom and despair. When that doesn't work, carrying a big stick helps, too.

Dark Priests use Magic and Cunning as their primary stats. They focus on Darkness and Arcane spells, and are proficient in staff combat, as well. They also have command of a unique kind of magic, Unhealing. Unhealing is negative healing and such functions differently than damage. It will not be affected by any type of damage mitigation and will be increased by the target's healing modifier.

Modifies the character creation dialog to bypass the lock check for races and classes, allowing characters to be created using locked races and classes. Doesn't actually unlock anything.

Frequently Asked Questions:

• Hey, the character creation dialog still says I have locked races/classes! What gives?
• Will this prevent me from unlocking things?
• The latest version of the game has a new locked race/class. Will I need a new version of this addon to access it?
• What the heck is this Runic Golem thing?

Plenum ToolTip: Enhanced tooltip display for ToME version 2.4 for ToME 1.3.0

This addon replaces the normal tooltip for actors in TOME with a more detailed description of monster abilities and characteristics. It adds to the standard tooltip detailed information on speed, main-hand, off-hand, and ranged damage, and damage modifiers and extra crit power, including damage penetration and damage affinities, plus retaliation damage, depending on what options are selected (from a tab in Game Options menu). This makes it much easier to inspect multiple monsters and quickly identify the most threatening. By holding a meta-key (ctrl, alt, or shift) and hovering the mouse over a monster, information on its status immunities and talents is displayed.

In addition, information on temporary terrain features (like smoke and darkness) and map effects (from spells and the like) will be displayed in the terrain tooltip if the appropriate options are enabled.

Combines several smaller utility addons, both for convenience and potentially reduced resource usage on smaller machines.

Adds the Mobility Generic Tree to:
- Rogues (Locked, 1.3 mastery)
- Skirmishers (Unlocked, 1.1 mastery)

This adds the Spell/Conveyance tree as a reward for completing the Tempest Peak questline for Angolwen. All the code is borrowed from DG's own, and thus everything works the same as antimagic characters getting Fungus.

Reworks the Rogue class.

This is a highly extensive "unofficial DLC" that takes the summonable creatures from the Summoner class and turns them into fully-talented, highly-comprehensive classes with their story and unique events.
This pack features the ranged summons: Hydra, Fire Drake, and Flamespitter Ritch.

• Disclaimer: This is NOT a full release. There WILL be errors and unpredictable behavior. I am patching things out actively, so play with discretion and send as much feedback as possible to the forum thread to accelerate the completion process!

Details:
This modifies the "Age of Ascendency" story, as you are no longer human, but rather, a natural, spiritual being. This means several conversations and services may become unavailable or even change to behave in new ways.
The plot's progression is mostly unchanged, but now you are operating under the command of an ominous individual known only as "The Summoner". He sends you off to do tasks-- But in the end, it is up to you to decide whether you will work cooperatively with him or not.
This was a labour of love, and I would want nothing more than for you to enjoy a new flavor of experience-- And a new type of challenge and difficulty in Tales of Maj'Eyal.
Please, enjoy!

Expanded Details:
"Hydra is a nigh-indestructible damage sponge that doles out as much as it takes, capable of attacking several times and several targets per turn. It possesses Feral, Glare, and Drool heads, each respectively associated with its Physical, Mental, and Magical wellbeing. You can choose whether you want to bite, stare, or spew your enemies to death-- Or maybe even some combination of such!"
"Fire Drake is a dedicated pet general, leading a batch of child fire dragons called 'Drakelings'. They are capable of growing and learning many of your talents-- But you must choose whether you will dedicate yourself to nurturing them, or making yourself powerful enough to protect them from the dangers of Eyal. Cooperation and good education is the key to success!"
"Ritch is a fullblown assassin, possessing a variety of techniques that want nothing more than for its victims to bleed, burn, and die to death-- And not necessarily in that order. Most significantly, they can craft and engraft bladed weapons to replace their claws, making them the only Avatar class capable of utilizing human weaponry. Killing is a skill, and you're good at it!"

Makes alchemists focus on creating elixirs that you are not currently helping them with.
In the base game, when you hand in ingredients to an alchemist, another alchemist completes one of his remaining elixirs at random.
What this addon does is remove the elixir that you are already helping them with from the possible elixirs to be chosen unless it is their last elixir.

Let your character to be an exotic weapon master:

  - Allows training of Exotic Weapon Mastery
  - Gives out more exotic weapons
  - The Library in Last Hope now sells exotic weapons

  - grayswandir's More Exotic Weapons
    http://te4.org/games/addons/tome/more-exotic-weapons
  - Effigy's Unlock Exotic Mastery
    http://te4.org/games/addons/tome/unlock-exotic

Plays beep sound when an NPC is killed.

You can change the pitch of beep depending on the NPC's reaction(hostile/neutral/friendly).
Options are found in Game Options > Misc, while in the game.

Adds useful items to the game. Currently supported:

• Single-use infusion patches for healing, detrimental effect removal and temporary speed.
• Scrolls of phase door, teleportation and controlled phase door.
• Rods of trap detection and disarming.

[NOTE:   Due to a game bug involving the transmogrification chest and activatable objects, we recommend that users of this addon also use the Activatable Object Cleanup addon.]

A complete rework for Bulwark.

Constitution now grants:
-+5 Life (Instead of +4)
-Critical Strike Shrug Off Chance (As with Dexterity)
-Life Regeneration
-Healing Modifier

In general, this mod is for people (like me) who like to do everything in a game. Visit all the dungeons, kill all the bosses, preferably get all the artifacts. By allowing all characters to visit some more restricted dungeons, we can make that a little easier. This mod is not intended to be lore-friendly, but I may make a lore-friendlier version in the future. (As it stands you can visit Irkkk as a halfling and the Yeek don't care. I may change that.)

Current mod features:
All characters can visit the Iron Throne, its shops, and its two attendant dungeons.
All characters can travel through the tunnel in the Ancient Halfling Complex to reach the Island of Rel. There they can visit Irkkk and the two dungeons.
All characters will receive caldera at level 20, and sludgenest at level 30.
The maximum level of Rel's dungeons is raised to match Halfling Complex (to 25)
The maximum material level of Rel's dungeons is raised by 1 (from 2 to 3)

A tweak to the Minimalist UI to visually indicate how much of your Displacement Shield has been absorbed.

Also available as part of the ZOmnibus Addon Pack and ZOmnibus Lite.

Adds the Gladiator, a warrior subclass. Gladiators are weapons experts and can wield one-handed weapons in either hand with ease, however they are also proficient with two-handed weapons and shields.
They learn many techniques for use with Axes, Maces, Swords and even more exotic weapons. Gladiators are able to quickly swap weapons and stack numerous detrimental effects on their foes, then finish them off with skills that grow more deadly the more devastated their enemies become.
Includes six new class trees and one new generic tree, allowing for a variety of builds. Will you wield maces and shields and wear your foes down while sheltered inside your armor or put defense aside, pick up a pair of waraxes and become The Axebutcher?
