Scourge of the Corruptor

73 melee damage 17% critical strike very fast speed average knockback 'A powerful javalin that unleashes tiny eaters'

Found in the hardmode dungeon's corruption chest. A spear shape projectile comes out, when it collides with a wall or enemy, it will do damage and spawn 3 tiny eaters. Tiny eaters will burst out in different directions from the spot hit, then appear to have heat seeking like movement towards enemies (if any is around).
