Burning Spell (Metamagic)
You cause creatures to take extra damage when you affect them with a spell that has the fire or earth descriptor.
Benefit: The earth or fire effects of the affected spell adhere to the creature, causing more damage the next round. When a creature takes earth or fire damage from the affected spell, that creature takes damage equal to 2x the spell’s actual level at the start of its next turn. The damage is acid or fire, as determined by the spell’s descriptor. If a burning spell has both the fire and earth descriptor, the caster chooses what kind of damage is dealt by the burning spell effect.
Using this feat increases the magic point cost of the spell by 3. The spell’s total cost cannot exceed your caster level.
