Bash: Clobbering
The Clobbering Bash upgrade makes a clobber guarantee a critical strike and leave the affected enemy Vulnerable for four seconds.
How it works
Clobbering is listed as a major Bash upgrade. The passage says clobbering an enemy with Bash has a 100% chance to critically strike and makes clobbered enemies Vulnerable for four seconds. The base Bash entry separately says every fourth Bash clobbers; that cadence is not presented as an effect unique to this upgrade.
