Pyromancer

Arkath's Rite of Flames:

A pyromancer cannot consult her repertoire normally. Any time she wishes to prepare her spells for the day, she needs to perform the Rites of Flames. The rite itself is simplistic, requiring the pyromancer only an hour of uninterrupted chanting and access to a flame of any size (a candle would do, although most pyromancers prefer large fire).

Doing so allows her to access her repertoire. If, for some reason, she cannot perform the rite, she is unable to use Ninjutsu. The rites of flames can only be performed once every 24 hours

Fireblessed (Ex):

A pyromancer is used to the flame, and the flames accept her as one. She gains resistance to fire equal to her Pyromancer level × 2.

Fire Manipulation (Su):

The Pyromancer has become so adept at casting fire spells, normal metachakra is easier to apply to the burning flames. At 2nd level, when you apply metachakra effects to spells with the [Fire] descriptor you decrease the total spell level by 1, down to a minimum of 0.

Persisting Flame (Su):

The Pyromancer's fire spells don't just do normal damage, they leave burns and pains on her enemies and their damage persists. At third level, anyone damaged by one of the Pyromancer's spells that has the [Fire] descriptor that dealt damage takes half the damage dealt again at the start of their next turn.

Expert Pyromancy:

When a 4th level pyromancer casts a [fire] spell, she may sculpt it as per sculpt spell without any increase in casting time or spell slot adjustment.

Arkath's Breath (Su):

The Pyromancer gains an inner reservoir of flames to call upon, allowing her to spew the flames from her mouth at her enemies. At fifth level, once every 1d4 rounds, she can use her breath weapon that deals 1d6/2 caster levels in fire damage in a 30 ft cone, usable as a standard action.
