Metamorphic Aspect
Warlord Trait: Lord of Unreality


Metamorphic Aspect - Proteus represents the myriad aspects of Tzeentch. At the beginning of each of your turns that Proteus is on the table (or when deploying him), before doing anything else, roll a d6; on a 2-6, choose one of his aspects to assume until your next turn begins. On a 1, determine one randomly.


1) Tentacled Horror
Flailing Assault - Proteus's Attack profile is changed to 2d6, and his strength for these attacks is equal to how many of the attacks hit, to a max of 10. Furthermore, he rerolls misses in close combat.
Binding Tentacles - Enemies in base contact with Proteus have 1 fewer attacks, to a minimum of 1.
No Escape - Enemies breaking from CC with Proteus have -2 Initiative for the purposes of Sweeping Advances.
Assault Grenades (not throwable)


2) Fiery Conflagration
All Is Kindling And Slag - Proteus's shooting and close combat attacks against non-vehicles have Soul Blaze, his Soul Blaze deals d6 hits instead of d3 (overriding Soul Blaze markers from any other source), and his shooting attacks have Melta.
Engulfed in Flame - Proteus has Feel No Pain against any Flamer or Melta weapon, and any weapon with Flame or Fire in its name, and once per turn, if Proteus makes his Feel No Pain against one or more such wounds from an opponent, he heals a wound suffered earlier in the battle. Proteus' unit may not receive Soul Blaze markers.
Fiery Wreath - After a unit resolves its close combat attacks against Proteus's unit, after all blows have been struck that round, it suffers a number of S2 AP- hits equal to how many hits it inflicted on the unit. These wounds do not count for combat resolution. This ability does not function for the unit while Proteus is in a challenge, but it will still work for himself and the hits will be S4.
Flames of Tzeentch x 2; Proteus may fire both in the same turn, and may target different units with these, but place both Templates before working out wounds.


3) Warper of Reality
Touch of Unmaking - Proteus's shooting and close combat hits against vehicles will each permanently reduce the AV of all facings of that vehicle by 1 (a vehicle with 0 AV on any side is Wrecked) on a 4+, and his close combat attacks against non-vehicles are made with the effect of a Mutating Warpblade.
Fluid Plane - Enemies treat all ground within 6" of Proteus as Difficult and Dangerous terrain.
Shielded from Realspace - Each time a shooting attack hits Proteus or his unit, roll a d6; on a 1, the attack is nullified.
Recrafted Reality - Once per phase, when a d6 roll (NOT part of a 2d6, 3d6, etc) is made within 6" of Proteus, by either player, you may force the die to be rerolled. (this may not be used to reroll what result is obtained from a randomized Metamorphic Aspect)


4) Muse of Insanity
Doubt - Enemy units within 8" of Proteus take all Ld tests on 3d6, dropping the lowest die.
They're All Against Me! - Each roll of 1 to hit Proteus or his unit in close combat strikes the attacker's unit instead of Proteus's.
Inspire Madness - As a shooting attack, Proteus may target a unit within 18"; the unit must make either a Pinning or Morale check, Proteus's controller's choice.
Uncertain Image - Units wishing to assault Proteus's unit must make a Ld check or they may not charge. Overwatch may not be used if the charging unit does not succeed on the check.


5) Nexus of Sorcery
Source of Magic - Proteus can Deny The Witch against powers targeting his unit or a friendly unit within 6" on a 4+, and if he successfully does so, he may immediately use the Denied power on the casting unit if it was a Witchfire, Focused Witchfire, or Malediction power (without expending Warp Charges or taking a psychic test); this 'bounced' power may be Denied as usual.
Gaze of Tzeentch - Proteus's Daemonic Gaze becomes Salvo 3/6.
Sorcerous Expertise - Proteus may forgo his usual shooting to choose a Warpcharge 1 psychic power from the Change, Pyromancy, or Telekinesis disciplines and use it; it does not count as the use of a psychic power, does not require expending Warp Charges or taking a psychic test, and may not be Denied or stopped with any other ability or wargear that specifically protects against only psychic powers.
Hit And Run


6) Scion of Secrets
War Table of the Foe - You may force opponents to reroll Reserve rolls and rolls to determine Outflank side. Once a Reserve roll's reroll results in a failure to enter from Reserves, this ability may not influence further Reserve rolls that turn.
Expected - When an enemy unit Deep Strikes within 12" of Proteus's unit, any one friendly unit within 12" of Proteus's (including Proteus' itself) may immediately make a shooting attack on it.
Ready and Waiting - At the start of the opponent's Shooting phase, choose a friendly unit; until the end of the turn it gains Counter-attack and may use its full BS for Overwatch.
Knowledge of the Field - If Proteus's unit triggers Mysterious Terrain, a Mysterious Objective, an Archaeotech Artefact, or any other table feature that is determined randomly upon a unit triggering it, you may reroll the result when determining its nature. You may add or subtract 1 from the result of your Warp Storm roll each turn. If playing a mission using Tactical Objectives, you may, once each turn, discard one of your Objectives and immediately redraw.
