See Module:DropTables/data to edit on the wiki. Notes[] Cannot be equipped with  Blunderbuss. Critical Deceleration is additive with similar mods. Tips[] Useful on shotguns with high base critical chance ( Corinth,  Corinth Prime,  Kuva Hek, etc), and if you do not mind the slight fire rate penalty (can be worked around with  Shotgun Barrage). Patch History[] Update 30.5 (2021-07-06) Critical Deceleration - Critical Chance from 48% to 200% -30% fire rate to -20% fire rate can no longer stack with Blunderbuss/Primed Blunderbuss*** If we release that... Maybe. Update 15.0 (2014-10-24) Introduced. See Also[]  Critical Delay, the Rifle counterpart.  Creeping Bullseye, the Pistol counterpart.
