Had an idea:

Phoenix Domain

Granted Power: All of your damaging spells or attacks deal +1d4 fire damage, and you gain Searing Spell as a bonus feat. This increases by +1d4 at 4th, 8th, and 12th, and 16th levels. At 20th level, you gain a permanent 5' radius aura of sun-fire that does 5d6 damage that cannot be reduced in any way to any enemy within its radius, as well as a permanent +5d6 bonus damage of the same type on all attacks or damaging spells. In addition, once per week, when you die, you may automatically revive 2 rounds later in a burst of fire, dealing 200 sun-fire damage to any enemy in a 20' radius.
