Firecracker

The Firecracker is a whip that is dropped from the Wall of Flesh with 12.5%/ chance. Like other whips, enemies hit by the whip are targeted by minions. The first enemy hit by the whip, or the enemy hit by the tip of the whip, takes full damage, and subsequent enemies will take increasingly reduced damage.

When a summon strikes an enemy when they are engulfed in the burning effect of the whip they will explode with energy, dealing extra damage.

It's best modifier is Legendary.
