the Anarchic Initiate PRC is almost like the wilder class with few more feats:
it gives you :
**+ to casting each level
**the Chaos Wild surge => when you use it, the reslt of the outcome of the psi-power you use depends on some %. i.e: if you got less than 50%, your power is halved (all it stats), more than 50%, it's empowered 100%+ it is maximized.
**psychic enervation =>(same as wild surge)
**calrity of confusion => +2 to saves vs effects with lawful descriptor ?
**postpone enervation
**Chaos breaches, minor and greater => works like anti magic field, but instead of nullyfying the spells/powers, it make them go wild if the casters fail their checks (the greater one actually can kill .. i think ?
)
all in all, not so much different than wilder (more selection powers maybe, depending on the starting class ?)
