Polarities Mod/Mollusc Staff

The Mollusc Staff is a Pre-Hardmode summon weapon that is rarely dropped by s. It summons a friendly mussel sentry that remains in place and lingers for two minutes before disappearing, firing bouncing pearls in sets of three in an arc that lands them directly on a stationary target. The pearls penetrate enemies and can bounce off of surfaces, slowly losing momentum as they bounce and eventually breaking on impact.
