Nihilism

Empty Mind:
The nihilist is a philosopher whose given up on the world to embrace the concepts of nothingness. They gain no extra spells to their formulae list, however they may always attempt to dispel or Counterspell a spell or spell like ability using an extract of equal or greater level. If the effect has no associated spell level use half the creator’s HD. If used to dispel magic this is administered as a touch attack as if an extract, however Counterspell is done normally. This replaces Philosophy.

Hollow Body (Su):
Nihilists often experiment on themselves, over time gradually destroying their bodies. They gain a bonus against energy drain effects equal to half their level and can survive without food, water, and air twice as long before suffering ill effects. This ability replaces mutagen

At 5th level they no longer need to sleep, eat, or drink. They also add their bonus to energy drain to poison and disease effects.

At 10th level the nihilist gains the No Breath ability and may turn partially unreal as if under the effect of Blink for a number of rounds per day equal to their level. While doing this they also treat gravity as subjective.

At 15th level the nihilist’s body is becoming more void than flesh, they gain a 15% chance to negate critical hits and sneak attacks as the fortification armor ability. This stacks with all other sources of such negation.

At 20th level the nihilist may use their Blink granted by Hollow Body for a number of minutes per day equal to their level.

Hungry Soul (Su):
At 3rd level the nihilist adds the bonus granted by Hollow Body to any effects relating to their soul and possession effects. If the nihilist succeeds at a save against a possession effect (Or similar) the creature who used it on them is still absorbed into the nihilist and is suppressed for the duration of the effect, receiving a will save equal with a DC of 10 + ½ nihilist level + Intelligence modifier each round to free themselves.

Maw of the Void (Su):
At 6th level nihilists can channel an abstract force of destruction through their bodies. As a swift action they may use Maw of the Void to add 1d3 damage per two nihilist levels to any unarmed or natural attacks they make, this damage is untyped and cannot be negated by anything less than DR/Epic. They may also expend an extract while using this ability to attempt to rend away all magic on a target, attempting to dispel an amount of spell levels equal level of the extract used. If the attack misses the extract is wasted.

Foreboding Call (Su):
At 9th level the nihilist can proclaim the end of all things. Making this proclamation is a standard action which affects everything within 10ft per nihilist level. This allows the nihilist to expend extracts up to a total extract level equal to his class level and attempt to dispel magic within the area until either an effect is destroyed, all targets have been affected without a successful check, or the total amount of extract levels have been used up as if using empty mind. The nihilist may do this once per day, then another use at 18th level.

One with Nothing (Su):
At 15th level the nihilist now automatically adds his damage from Maw of the Void onto all his natural and unarmed attacks. Additionally they add their bonus from Hollow Body to caster level checks to dispel when using this ability, and may attempt a special Counterspell to attack a spell effect within their reach with this dispel check. In either case if the spell is negated they gain a bonus to their Maw of the Void damage equal to the spell’s level.
