ACS12 - Corrosion
A close-range Power Surge weapon that converts multi-pellet hits into explosive status pressure. It benefits from getting close enough to land full shots, then stacking Crit and Power Surge support rather than treating it as a conventional weakspot shotgun. It is especially suited to burst windows on durable enemies.
Special Perk Mechanic: Power Surge
Corrosion is a Power Surge shotgun. Its pellet hits can trigger Power Surge without applying the normal status to non-Meta-Human targets, while its special interaction allows Power Surge to critically hit. Power Surge damage gains an additional 15% factor.
