The Devourer Staff is a craftable Pre-Hardmode sentry summon weapon. It spawns a Devourer at the player's cursor that lobs eggs straight into the air, which hatch into 4 tiny eaters that home in on the nearest enemy to deal damage. The eggs themselves break on contact with a tile or automatically after 1.5 seconds, and cannot deal damage.
Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, Minions cannot deal critical hits. The only significant advantage a Mythical Devourer Staff has over a Ruthless one is knockback.
