Alright, so this is two parts. A new zone, and a new class that you unlock by finishing said zone.
You should get an in-game item that explains some things.

Illusory Wood
You'll find this place a couple spaces east of Zigur. Minimum suggested level is 18.
Complete the quest inside and you'll unlock the Trickster class.

Trickster
A psionic rogue.
- Use illusory walls and decoys to distract your enemies.
- A wide variety of debuffs that confuse and distract your foes.
- Turn enemies' confusion into your own power.
- Convince your enemies that they don't see you, even as you stand in plain sight.
- Stabbing things.
The basic idea is that you throw out illusions everywhere to cover you while you stab things to death.

Feel free to offer suggestions/feedback/whatever.

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?

The Lost City of Vulcus

Some events in history are of such importance and have such wide ranging ramifications that they become fixed points -- junctions in time that must and will happen in order to maintain the integrity of the chronoverse.

Lost ages ago, Vulcus was considered by many to be the greatest center of Dwarven learning below the surface. Even up until the fall of Reknor in recent times, however, Dwarven innovation and breakthroughs continued, seemingly by miracle. Fate, however, dictates that one of the greatest untold secrets of the Empire cannot remain hidden forever. Perhaps you will be chosen to take part in this crucial point in history -- to reap the rewards or to suffer the consequences.

This addon incorporates a new major event (like the drake cave or fearscape invasion portal) that has a chance to occur (possibly more than once) on each level in various zones (Infinite Dungeon, Spellblaze Scar, Ardhungol, High Peak, Reknor, Shadow Crypt). Within the game, this event is most like a combination of the Lost Merchant and Limmir quests, and is intended to replace those for characters in the I.D.

Recommended level 10+ (depending on class). The intended difficulty is slightly higher than the Limmir quest, and there are gradations of success. Participating in the event when it spawns is completely optional and you can do it later if desired.

This is possibly the most complex encounter in ToME, with a large number of NPCs, enhanced AI, and various terrain effects. It is compute heavy and will tax slower computers (even with reduced graphics settings).

The basic idea behind the class of the Forge Knight is that of armor and weapon crafting. While item manipulation is already part of the game in form of some talents like Stone Alchemy's Imbue item or Finer energy manipulations' Reshape Weapon/Armour, class talents of the Forge Knight go one step further and allow the recreation of a piece of armour (body, helm, shield) or weapon (metallic, non-archery). The underlying crafting process is pretty simple: an existing item is being used as raw material for the creation of a new item of the same basic type and subtype. The original item is being consumed during the crafting process. Crafted items are initially basic items (white display colour) enhanced by certain bonuses like combat damage or armour and defense values. The development of passive talents allows for a broader spectrum of enhancements on the crafted weapon. Eventually, a Forge Knight learns to craft items with innate extra properties, like a developed ego (green/blue/violett display-colours) and powerful talents, which the Forge Knight gains access to while wielding the crafted item .

In addition to two talent types dedicated to crafting (weapons, armours), the Forge Knight gets two additional unique talent types (class, generic) covering combat and passives, as well as several talent types from those normally available to members of the warrior classtree.

The class idea was partly inspired by the concept of the Enchanter class in Arcanum from House Pet, which I had alot of fun with, and the desire to build a variation of a smith-class, which doesn't exist so far in Maj'Eyal.

Addendum:

- Fixed compatibility with grayswandirs weapons pack: alternative damage modificators are now enhanced too.
- Bonuses now scale with ego-multipliers: Two Handed Weapons get slightly better bonuses, daggers slightly worse.
- Added/changed on-hit-talents.

Reduced Abuse:

- any antimagic item that is being used for forging will result in forged items with an antimagic powersource
- if reforging uniques, that are infused by arcane powers, the reforged unique will also be infused by arcane powers
- all forged items are now considered being either egoed (green, blue, violet display colour) or rare (brown display colour)
- points invested into the talent trees of armor and weapon forging can't be redistributed afterwards anymore (no 'respeccing' in towns)

Revision:

- removed access to regular shield/dualwielding/2handed-talent-trees from the Forge Knight
- added two new talent trees, that cover combat skills that work regardless if you fight using a shield, dualwielding or with a twohanded weapon (albeit with different effects)
- added the ability to switch weapon sets without spending a turn, so Forge Knights can make most use of all the weapons they are able to craft, depending on situation

Refine & Restore:

- Refine Items: Learning or putting a point into the talents "Armour Forging" or "Weapon Forging" gives access to a skill, that lets you upgrade your forged items towards your current skill level in the different talents of the forge group. Only properties that were put onto a forged item via the forge-skill previously will be affected and only items that have been forged after this patch can be refined.
- Restore Artifact: Learning or putting a point into the talents "Artifact Armor Design" or "Artifact Weapon Forging" gives access to a skill, which lets you reverse forging on an unique item of lore (golden display colour) once - to recover the original artefact. Only artefacts reforged after this patch can be restored.
- Fixed an error that would come up if forging items "of the deep".

Forbid Nature / Arcane:

- If you are too distant to nature (e.g. undead), you won't forge items which grant you wild-gift-talents anymore (unless you forge items powered by antimagic forces).
- If you are a follower of zigur, you won't craft items which grant you spellbased-talents anymore.
- Distribution of cd-reductions and talent-masteries on items hasn't been changed and stays completely random

Refinement Fix:

- Fixed an issue, where after refining an equiped weapon or armor some properties (like resists) wouldn't be registered properly
- Power Catalyst: Mind now helps you regaining lost equilibrium when resting

Small Fix (15.01.2015):
- Prevention measure related to a reported lua error

Fix weapons_of_projection (24.01.2015):
- forged weapons with the ego "of projection" should now cooldown properly
- no more lua errors incase you you have a weapon without material level (tier definition) in your inventory

Let there be Gnomes!

Addon-content:

1. New subrace: Gnomes (included: own starter-zone and quest)

2. Additional zones and quests:
a) Midlevel zone & quest (15-20): starts near Last Hope, related zone has to be found on the worldmap
b) Highlevel zone (35-50): a hidden zone, that can't be entered by normal means / a quest starts inside, on the 2nd level

About Gnomes:

Gnomes are distant relatives of Halflings, albeit a tad smaller in stature and much weaker physique. In the world of Maj_Eyal, not much is known about them for simple reasons: they usually don't leave home to go on adventures, much less to take part in heroic endeavours. People commonly mistake Gnomes for extraordinary small and malformed Halflings, even if that is far from being the truth. The existence of Gnomes as a proper subspecies has passed history unnoticed for centuries, while they lived peacefully, silent and hidden within Halfling society, dedicating their lives to the study of the physical, magical and historical dimensions of Maj'Eyal.

In theory, however, gnomes make great adventurers. While they lack any of those physical attributes, that are commonly associated with a lifestyle dedicated to performing heroic deeds, they got the ability to gain advanced knowledge about almost anything related to skillful adventuring. They start their career with two instead of just one racial talent trees and are able to learn new talent types not available to their choosen class. As a result, they make for very flexible game play, but they are challenged by a low life-rating.

--- Major Revamp as of 20.12.2014 ---

! ! ! ! ! No compatibility with older versions ! ! ! ! !

Gnomes now offer a truly experimental game experience. Gnomes get two racial trees:

- one tree allows them to learn just about any talents associated to different meta themes (they can learn one type each of these groups: technique/cunning, spell/celestial/chronomancy, psionic/wild-gifts, cursed/corruption).

- the other tree provides general offensive and defensive benefits as well as resource (stamina, mana, psi, equilibrium) regeneration.

As a result, playing as a gnome makes it possible to spice up just about any class with new talent combinations normaly only experienced when playing the Adventurer class.

Additonaly, gnomes still start with their Gnomish Pocket Encyclopedia - an item, which at level 30 allows them to pick one further talent type from about just any category (excluding stone wardens talents).

Specifics - Stats and Racial Talents:

Stat modifiers: -4 Strength, +1 Dexterity, -6 Constitution, +1 Magic, +0 Willpower, +6 Cunning, +0 Luck
Life per level: 6
Experience penalty: 10%

Update (24.01.2015):

- added a visual distinction between generic and class trees in the dialogues where you choose which talent-type to learn
