Various enhancements to escort quest NPCs:
- Escorts now follow the player when not close to the portal.
- Escorts occasionally say useful things.
- Escorts heal 5% of their maximum health per turn.

Adds an alchemy table to the Infinite Dungeon, that appears with roughly a 50% chance at each floor. Here you are allowed to brew potions (similar to those achievable from the alchemical brotherhood) and transmute items into artifacts (rewards and costs are somewhat similar to the quest-mechant from Last Hope, though there is a price-scale). Depending on what you pay for, transmuted items keep their item tier (option: lesser) get a bonus of one (option: greater) or two (option: superior) item tiers. When transmuting tier 5 (option: greater) or tier 4 and higher (option: superior) items, these become extraordinarily powerful.

Version 1.1

Brewing potions additionally consumes gold now (starts at 0, +125 / created potion)

Adds Wilder and Psion escorts.

Allows the player to pick multiple classes, turning all enemies into Randbosses as a counter-measure.

In order to activate this addon, look at your Game Options for a new tab.

Updated Version 1.4.1:
- Possessor and Adventurer can now be chosen in the Multiclass menu

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.

Other addons that affect these files might not be compatible.

Allows you to choose which escorts you will encounter at the start of the game.
You may change the future encounters in the game menu (Esc).

There is an option to choose a random escort in case you just wanted to guarantee some unlocks before continuing with the base game's behavior.

Note: You're only supposed to be able to choose the lost tinker once. (Must have the Embers of Rage DLC and unlocked by playing in the Orcs campaign)
Note: Unfortunately the only time that addons can get the possible escort types is after the random escort quest is assigned.
This means escorts added by other addons will not be available for selection, but will still be possible to find using the random selection.

To reach me faster, please leave a message on the Steam Workshop page. I don't get notifications on te4.org so I may take longer to reply.

Adds the White Monk, a warrior subclass.

The White Monk wields no arms, instead using intense focus and training to turn their body into a weapon. They fend off enemy blows with their immense willpower and can preform healing and regenerative rites. Primary stats are Dexterity and Willpower. White Monks have the unique ability to project unarmed melee attacks at a distance, with talents that allow them to strike many targets in a area, as well. White Monks have a base damage modifier for hand gear of 60% Dex and 60% Wil, and gain some of the same benefits to unarmed attacks as Brawlers.

Includes seven new talent trees and incorporates a few existing trees from Warrior and Rogue classes.

Rending - Attack your foes from afar and sap their energy.

Mending - Heal and cleanse yourself and even prepare a rite that can ward off death itself.

Fending (generic) - Ward off enemy assaults, directing some damage to your stamina pool.

Agile Combatant - Move across the battlefield with unmatched agility.

Martial Arts - Master the art of unarmed fighting and gain bonus strikes from your attacks.

Black Belt (locked) - Learn advanced fighting techniques to cripple your foes and react with finely honed reflexes.

Transcending(locked) - Directly manipulate your foes' spirits to sap their energy and learn to project your spirit to assail all nearby foes.

Follow one of the Six Ways with a set of class evolutions for the White Monk:

Way of the Rushing Bull

Way of the Flying Arrow

Way of the Open Palm

Way of the Arcane Flow

Way of the Transcendent Spirit

Way of the Hidden Viper
