1. Burning magic only affects 3 spells for a Oracle with only core spells (APG spells are a unknown factor)
Fireball, Flamestrike and Firestorm.
In my eyes that is not enough to make this otherwise very cool revelation worth anything. Maybe allow it to be applied to the damage dealing revelations too? (Maybe the APG adds fire damage dealing, reflex halving spells for clerics. favorably about 1 per level, that would solve the problem)
2. Oracles of fire don't get Fly as a class skill, but have a revelation that gives them a fly speed. This is not really a problem, but seems to be a change from MO, so I mentioned it.
Maybe it's just an oversight, maybe it is intended as it is. Either way I'm cool :)
