Kiss of cathari

Good morning, regarding stun counters, are they cumulative or, regardless of how many counters a vampire possesses, do they all resolve in the same turn?

I believe the answer to your question is here:

NEW TERMS
Stun: lock a minion and put a stun counter on them. A minion with one or more stun counters does not unlock as normal at the beginning of their controller’s unlock phase; during that unlock phase, burn all stun counters they had at the beginning of the turn.
