Chaos Champion

Although the powers of Chaos are indeed foul, there are those who willingly choose to serve and follow them.  The promise of easy power and seductive blandishments of Chaos can prove too strong for many minds.  And so there are those willing to ally themselves with the Dark Powers of Chaos.  The commitment is total:  body and soul belong to Chaos.  Followers of Chaos give up all vestige of their former Humanity and become Champions of Chaos - the warriors and sorcerers who ravage across the the galaxy in the name of one Dark Power or another.

Mark of Chaos: This is dependent on the power the Champion serves. 

Khorne: The character immediately receives a suite of Khorne Gothic Armour.  Spellcasters lose the ability to cast their highest level magic (so a 20th level Wizard Champion of Khorne would not be able to cast any 9th level spells. But they receive the Heavy Armour Feat for free.

Slaanesh: The character can cast the spell suggestion as a caster equal to his total levels (per the PHB). This is a spell like ability usable once a day. 

Nurgle: The character receives the supernatural ability Disease Immunity.

Tzeentch: Fortune, may re-roll 1 dice a day. 

Chaos Gift: Roll a random Chaos Gift from the Gamma World Mutation table in Dungeon issue #94.

Chaos Attribute:  Roll 1d8 to determine the attribute affected (1 being STR, 2 being DEX etc.).  Khorne Champions receive a -1, Slaanesh Champions receive a +1.  Tzeentch champions receive +1 or -1 on the roll as they wish.  They may apply it after the roll is made. Then roll 1d6-1 to determine how much that attribute goes up (or down).

Prince of Chaos: The character transcends the boundary between humanity and the Warp and becomes a Daemon Prince.  Apply the one of the following templates to the character (characters choice) Fiendish, Lich, Half-Dragon or Ghost template to the character.  He or she is considered an Outsider or Undead from now on.  The character is immortal and no longer ages (but can still be killed).

Khorne Gothic Armour: The armour is designed to look like appropriately Gothic version of Khorne. It is equivalent to TL 13 Power Armour with the following additional benefits; Moderate Fortification and inbuilt Warp Claws.  The claws are retractable and maybe used as melee weapons.  They inflict as 1d10 dmg (x2 critical) and if the hit penetrates the armour it triggers Frenzy in the affected character who fails a Fortitude vs. DC 14 save.  Frenzy is equivalent to the first level barbarian ability.
