[[Image:Skill_witchdoctor_firebomb_icon.gif|left|Firebomb Skill Icon]]This skill allows the WD to lob blazing projectiles, like molotov cocktails, at his enemies. They may be thrown varying distances, from most of the way across the screen to nearly at the WD's feet. The burning bottle tumbles end over end in mid-air, and explodes with a burst of flame when it lands, dealing fire damage and knocking back anything in the immediate vicinity. The spell seems to involve some sort of fire spirit, not just a flammable substance, since a flaming figure is briefly visible overhead when the firebomb bursts. It also sets targets aflame, and they take continued damage from the fire for several seconds. There are fires left burning on the ground after a firebomb detonates, but these do not seem to deal damage to, or set fire to, targets that walk through them.

Like the locust skill, the firebomb skill may also be cast upon minions, which will add fire damage to their attacks.
