" Equip: Your harmful ranged spells and abilities have a high chance to rouse the lantern’s flame, granting a stack of Lamp Light up to 15 times. After 30 sec of collecting stacks, Lamp Light is consumed to attract an equal amount of Fireflies to charge the next target you attack exploding for 151 Fire damage per Firefly."
