My GM has decided that OAs happen in an arbitrary order with respect to persons making the attack, instead of all at the same time — and the order isn't even in the order of initiative. I was under the impression that all OAs on a target happened simultaneously. Is this not the case?

The specific example from our game is that in response to my movement, a monk punched me and then a cleric cast "Command" (via Warcaster feat) on me, both using their OAs.

I argued that the Command spell shouldn't work in that circumstance for a bunch of reasons.

1. The spell says that its effect happens on your next turn, not the same turn.

2. The command was to "Grovel" and it put my character in danger, namely from the Monk's punch and the fact that my PC was surrounded by enemies.

Even assuming that each of those opportunity attacks was valid, is it correct that the opportunity attackers get to decide the order among them?

In a game I am playing my GM decided that OAs happen in arbitrary order of the person doing the attack, instead of all at the same time — the order isn't even in the order of initiative. I was under the impression that all OAs happened simultaneously. Is this not the case?

Aside, I argued that the Command spell shouldn't work in that circumstance for a bunch of reasons.

1. The spell says it happens on your next turn, not the same turn.

2. The command which was to "Grovel" put my character in danger, namely the Monk's punch or the fact that they were surrounded by enemies.

But assuming each opportunity attack was valid, is it correct that the opportunity attackers get to decide the order?
