Obtain a Clacking Claw
Farm a Clacking Claw from Klakatak in Zaralek Cavern. The buff it grants lasts 10 minutes, so prioritize killing as many rares as possible while it is active.
Kill rares with buff active
Join a raid group to efficiently tag and kill rares across Zaralek Cavern while the Clacking Claw buff is active. If you have already killed some rares on your character, grouping with others lets you credit rares you have already done by tagging fresh kills.
Complete all rare kills
Once all rares in Zaralek Cavern have been killed while the buff was active, the Cavern Clawbbering achievement completes and awards the Vibrant Clacking Claw toy.
Tips
The Vibrant Clacking Claw shares its cooldown with the regular Clacking Claw — both have a 1-hour cooldown and 10-minute duration, and using one puts the other on cooldown, so you cannot stack them for extended uptime.
The Vibrant Clacking Claw does not satisfy the Lord Stanley encounter requirement; the actual Clacking Claw item is required for that.
