A character who has Break the Bell appears to be upgrading all "Staggered" afflictions on targets they hit to "Dazed." This occurs on normal attacks, and consumes no class resources-- any enemy that is already Staggered becomes Dazed when the BtB-having character hits it. The enemy's status description then attributes the Dazed affliction to Break the Bell.
See save linked below. Aloth (a Spellblade) has BtB. Rekke (Brute) has Spirit Frenzy, which helps apply lots of Staggered afflictions. They are standing near some Bad Doodz for testing. (Yeah, I'm doing Hasongo unusually late in this run.)
