Just for the record, because I boosted on the second action all boosts apply until the end of the next round, not a flat 3 actions.
If I had charmed on the first action, it would have been -1 the whole next round. Second action, the rest of the next round as well as the current round, and third action is the rest of the next round also. It's more effective to do all boosting moves on the second or third actions of a round.
