Currently deals: Knock down, 6 seconds confused and eye blurry on human mobs, 6 seconds weaken on silicons and applies 85 brute damage to all mobs. Scales with range, at 2 tile range deals roughly 40 damage Cooldown is similar to fireball, as in pretty fast since it also requires a condition of a corpse to be casted.
