First time GM here wondering how you guys handle damage over time stuff.

I have an enemy designed called the Silk Sorceress. She attacks by magical manipulating sashes of silk, making them move on their own, become impossibly sharp, grow in size etc.

I have a move written where a sash wraps itself around a players neck and becomes impossibly heavy slowly choking them. I know how that works fictionally, they can’t move, their vision grows dim. I’m kind of confused how damage gets applied in that situation since there aren’t really turns like in traditional games. Is it just a matter of rolling a dice when you check in with them? or should I do it as a hard move on a -6. how much damage is appropriate. I want to give a sense of urgency while still giving my players so opportunity to react?
