Your contract is one with the cosmos itself. The primal forces of evolution have manifested within you; your barrier separates the fit from the unfit and your beam decimates those who would defile the natural order.
Barrier Effect: Contractors with the evolution contract select a favored enemy (see below). At 1st level, when a favored enemy enters your barrier or is in the area when you project it, it must make a Will save or become monitored by you as through the status spell. This effect ends when the creature leaves your barrier. A creature who succeeds on this save is immune to this effect for 24 hours.
Contract Powers: The following are the granted powers of the evolution contract.
Favored Enemy (Ex): At 1st level, you gain the favored enemy ability, as a ranger of your level.
Extinction Beam (Su): At 4th level, your favored enemy bonus applies to the DC of saving throws your favored enemies must make against your beam attacks.
Sphere of Extinction (Su): At 8th level, your favored enemy bonus applies to the DC of saving throws your favored enemies must make against your barrier effects.
Erase Blight (Su): At 12th level, your beam ignores hardness and deals maximum damage when affecting mundane unattended objects and structures created by your favored enemies.
Ruthless Onslaught (Su): At 16th level, when you deal damage to a favored enemy with your beam, you may make a free Intimidate skill check to demoralize all creatures of its type within your barrier. Only creatures who can perceive you are affected.
Casshern's Lightning Bolt (Su): At 20th level, your mission to ensure the natural order takes you from the here and now, carrying you across time and space. Once per week, you may plane shift, as the spell. You may not bring any creatures with you when you do this. In addition, you gain the constant benefits of planar adaptation. Each time you shift planes, you may change one of your favored enemy types to another type, keeping all bonuses static.
