You cause creatures to take extra damage when you affect them with a spell that has the fire descriptor.
BENEFIT
The fire effects of the affected spell adhere to the creature, causing more damage the next round. When a creature takes fire damage from the affected spell, that creature takes fire damage equal to 2x the spell’s actual level at the start of its next turn.
MP Increase: +2 (a burning spell costs 2 additional MP more than the actual MP cost of the spell.)
