I'm a bit confused with the token mechanics. A paladin of mine has a cursed corset and it says "Start turn with 5 (corset icon) token: 0/1"

The "corset/posture collar/heels of education" have a chance each turn to add a semi-permanent token that persists through dungeons. The token can stack up to 10x, but in order to uncurse the item, you need to start a turn with 5 tokens.
Edit: those tokens have a chance to be reduced by 1 by NOT wearing any corset/posture collar/heels.
