Eternal Flame (3.5e Invocation)

Duplicate the effects of continual flame. You may also dispel any fire effect as if using greater dispel magic with no cap on caster level. You always succeed dispelling your own continual flames and mundane natural fires in a 10 ft. cube area at a time.

Finally you can make a fire effect permanent. As a standard action you can effect any fire in 30 ft. and make it continue burning long after its fuel source, magical effect, or even oxygen supply has run out. You can affect one object or spell, or up to a 5 foot cube per level, whichever is smaller. You may only have one permanent fire in effect at one time per point of Charisma bonus, making another fire permanent requires you to release permanency on a previous casting as a free action.
