Adds all races available in the Arena campaign to the Orcs campaign. You will still need to have a race unlocked in order to play it in the Orcs campaign.

This should work for all DLC races and most addon races, assuming they are not implemented in an unusual way and their addon weight is lower than that of this addon (200000).

Many in Maj'Eyal have heard of "demons", sadistic creatures who appear seemingly from nowhere, leaving a trail of suffering and destruction whereever they go. Their Fearscape floats far above the skies, watching and waiting, but not idly; their agents scout the land, their legions build up their forces, and their scholars develop new spells and strategies. As the barrier between our worlds begins to crack under their scrutiny, helpless Eyalites have begun to disappear, whisked up to serve as their slaves and playthings. They imbue these victims with magical powers to better survive the ensuing stresses - can you use your new-found abilities to escape the legions of Mal'Rok?

Features:

• Start with a new class, the Doombringer! These avatars of demonic destruction charge into battle with massive two-handed weapons, cutting swaths of firey devastation through hordes of opponents. Armed with flame magic and demonic strength, they delight in fighting against overwhelming odds, softening up the crowd with waves of fire, then feeding on the flames and suffering of their surroundings to stay alive while quickly reducing any group to a pile of ash and gore.
• Unlock a new class, the Demonologist, with an all-new item enhancement mechanic! Bearing a shield and the magic of the Spellblaze itself, these melee-fighting casters can grow demonic seeds from their fallen enemies. Imbue these seeds onto your items to gain a wide array of new talents and passive benefits, and summon the demons within them to fight on your side! Ever looked at a gigantic demon-cursed minotaur and wished it was on your side for once? Well, now you CAN summon one to pound your foes into paste while you cast devastating spells from afar, or call forth a squad of Fire Imps to pelt your enemies to death while they exhaust themselves on your impenetrable defenses! Demons have persistent health, making them a little more precious than disposable necromancer skeletons or summoner beasts, but can be revived from death nonetheless.
• Two new zones, with all-new art, foes, and bosses! You've seen the plains of the Fearscape before, now see the lairs and headquarters of the demons themselves!
• Over 10,000 words of written lore to find! The demons were once an enlightened, peaceful race, hailing from a distant planet known as Mal'Rok; learn what drove them to plot Eyal's eternal torture! Discover monuments to each of the demonic species and noteworthy individuals, showing the place of honor each has among them! Get a glimpse into the culture and daily lives of these sadistic invaders and their brainwashed thralls!
• Unlock a new race, Doomelves: Shalore who've taken to the demonic alterations especially well, corrupting their typical abilities into a darker form. Blink away to safety, transform into a shadowy dúathedlen to hide in the shadows or prey on your foes with blasts of darkness, use your new resilience to soak up status effects and critical hits, and assault your enemies' minds to leave them unsteady in combat!
• Between the aforementioned classes and Doomelves, a whopping 75 new talents!
• Unlock two new cosmetic options! You know you've always wanted demon-horns.
• Two new events, appearing anywhere in Eyal!
• 20 new artifacts, with unique and interesting effects. Collect the Obsidian Treasures to amass more and more power! Slip your hands into the Will of Ul'Gruth and watch your sweeping blows smash down walls! Wear a giant hideous hell-mouth as a fashionable belt!
• 7 new achievements! Conquer the worst Urh'Rok's forces can throw at you, and hang their metaphorical skulls from your profile page!

One year has passed since the one the Orcs call the "Scourge from the West" came and single-handedly crushed the Orc Prides of Grushnak, Vor, Gorbat, and Rak'Shor.  The Allied Kingdoms, now linked by farportal to their distant, long-lost Sunwall allies, have helped them conquer most of Var'Eyal.  The few remnants of the ravaged Prides are caged...  but one Pride remains.  Kruk Pride, isolated on an island, is the last orcish settlement that stands; they, too, face their impending doom.  The Sunwall has blockaded the only exit point from the island, and now, the technologically advanced civilization of Steam Giants have come down from the mountains to take their homeland with machines and weaponry unlike anything else on Eyal.  Kruk Pride has reverse-engineered their technology before; their only hope is to do it again and rise up against the Pride's foes.
 

Features:

• Explore a whole new campaign from level 1 to 50, one year after the events of the original Tales of Maj'Eyal campaign. Liberate the Orcs (or die trying) by rising up against the Sunwall, the Steam Giants of Atmos, and other dangers that may lie in wait...
• Play as one of three new races: the battle-hardened Orcs, the brutal Yetis, and the unstoppable Whitehooves. Discover their stories, their pains, their hopes... and their awesome racial powers!
• Risk your life in over 20 unique zones! Explore the ruins of a lost city, lay siege to the Sunwall forces at the Gates of Morning, and raid the Steam Giants' mining quarry - each has its own unique foes and hazards, leading each to feel and play different from the others.
• Play as one of the four new tinker classes: Gunslingers, Sawbutchers, Psyshots and Annihilators! Plus a class evolution: Technomancers! Crush and rend your foes with heavy metal, electrocute and immolate them with your gadgets, charge across the battlefield or nimbly strafe in style - each plays differently, and none provide any shortage of ways to slay your foes.
• Master steam technology to build powerful tinkers to augment your equipment. Need to close in a bit quicker? Turn your boots into rocket boots! Having a hard time deciding whether to shoot someone or stab them? Build a Hand Cannon into your gloves, or deploy a Weapon Automaton to do the stabbing for you! If you have a problem, steamtech has a solution, usually involving explosions; with over 80 different powerful contraptions to craft, enjoy unparalleled versatility and trying something different with every playthrough.
• Master the tactical uses of over 140 talents! Fire bouncing trick-shots and psychic-infused shots, use your steamsaws as shields or wheels, terrify your foes with long mechanical arms - there are no "boring" talents here, everything has its own special applications and properties!
• Use advanced technology in the world of Eyal! Burrow through sand, plant bombs to destroy tunnels, and discover that you aren't alone in using it...
• Infusions and runes are for puny humans; implant new medical injectors to pump an array of experimental chemicals into your body! Injectors can use any (infinitely reusable) salve in your inventory as long as they're off their cooldown, giving you versatility you've wished you could get with a couple of inscriptions.
• Loot over 70 new and powerful artifacts. Pump lead into foes with big guns, quick guns, and explosive guns! Shred them with saws that maim, saws that thirst for blood, and saws that aren't really saws! Violate common sense by strapping a rocket to your back and calling it a jetpack!
• Enjoy dying in horrible and exotic ways at the hands (or claws, jaws, guns...) of over 140 new creatures! Not mere piles of stats and chain-stuns, these foes will provide unique challenges - suffer the Sunwall's newest cosmic spells, the new breeds of ritches that infest and multiply, the Steam Giants' elaborate defense systems, and find new strategies to adapt to each!
• Earn a trunkload of achievements! Have your accomplishments recognized for liberating the Orcish people, displaying exceptional mercy or cruelty, or showing your prowess with impressive feats! Give a boss a fate worse than death, show Sunwall forces how frustrating it is to fight a Radiant Horror as a paladin, come out on top against impossible odds, display a suicidal lack of situational awareness, and wear a badge of pride or shame for each!
• Read roughly 27,000 words of new lore to immerse yourself in the world! Learn how things have changed since the Scourge's campaign, feel hatred and/or pity for your foes, uncover grand schemes and sinister plots, and notice the elaborate connections between Var'Eyal's numerous factions. Every zone has a story behind it, and every story ties into a bigger picture; enjoy a tale of horror and humor, of intrigue and glory, of despair and hope.
• Earn the right to use the classic (and Ashes of Urh'Rok) classes in Embers of Rage, and the new tinker classes in Maj'Eyal! Play a Brawler in the East to fulfill your life-long dream of suplexing an entire nation of giants, or play a Sawbutcher in Maj'Eyal to shred through Dreadfell in a whirlwind of sawblades and steam!

Adds two races, one class, a new town, and a new low level dungeon. Completing a quest to explore the new dungeon unlocks purchasable perks in the town. This quest is the starting quest for the added races, but anyone can access an alternate version of the quest with the same rewards. Look toward the coast east of Last Hope to get started.

Available perks (cost varies):
Reveal Exotic Weapons Mastery (must already know Combat Training; Combat Training can also be purchased as per Last Hope shops).

Gain the ability to invest in Heavy Armour Training and equip mail(heavy) armor by meeting the requirement with the highest of Constitution and Dexterity (or Strength, as usual).

Gain bonus attack and movement speeds and a chance to evade incoming damage while wearing mail(heavy) armor. These values scale with Dex and Con, respectively.

Learn (locked or unlocked) a new Psionic/Mindstar combat talent tree. Similar to Wild-Gift/Mindstar mastery, this tree also has a Psiblades sustain. Once learned, you can also pay to boost mastery (as with Mindstar mastery from Zigur).

---

Psionic/Mindstar combat:

Psiblades:
Increases damage and physical power when attacking with Mindstars. When sustained, increases the damage modifiers and mind stats granted by equipped mindstars (this is an exact copy of the wild-gift/mindstar mastery psiblades talent).

Mind Thorns:
Instantly touch the mind of an adjacent foe, creating mental thorns which reduce mind save and deal mind damage each turn for a few turns.

Mind Storm:
Create a storm of psionic energy which lasts for a few turns. The storm will overheat the mind of foes in the area, causing them to burn (stacking). Allies in the area will be obscured by illusions, reducing the bonus damage of critical hits dealt to them.

Attack an adjacent enemy with your mainhand Psiblade and channel the energy through your offhand to create a psionic damage shield around an ally or yourself. The power of the shield is based on the damage of the attack and can be a mental critical. The shielded target will also regain an amount of Psi based on the damage of the attack.

 Small edit done by me that nerfs enemy talent level scaling across the board. I take no credit for this great rework of the original Multi-Class challenge, all credit goes
    to AscendingPhoenix, find the orignal mod here: https://te4.org/games/addons/tome/dual-class-challenge

Allows the player to pick two classes, but the difficulty scales upward. The mod dramatically ramps up the difficulty level to compensate. (Original by StarKeep, forked mod by Raenarill).
You advance twice as fast, and gain six talent category points: at 10, 20, 30, 40, 50, and 60. You gain normal stat points until level 51.
BLITZ MODE: You gain two thirds more talent points. After level 66, you gain one class talent point per level and one generic every two out of three levels.
CLASSIC MODE: features base game talent points until level 100.

CLASS EVOLUTIONS: You can swap your first and second classes in the Game Options tab for evolutionary purposes.
WANDERERS AND ADVENTURERS: These are only supported as the FIRST class.
QUANTUM SLIDERS: Now supported as the second class.
EXPERIENCE ADJUSTMENT: You can now adjust how much experience you are gaining, from 50% all the way up to 500%.

TIP: Good equipment takes the usual time to show up, so you probably will see it at about lvl 50 with dual classing enabled.

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