Using the Stunning Rumble in the Steel Pretter's Attack

When the creature is stunned, it is a juicier target for the steel pretter. What it really wants to do is stun its main target. It's ee going to have this relef the usion itself. Even though its intelligence is four, it's still considering how many targets it might be able to hit with its roar. Ah, when has a second opportunity to use the stunning roar? I think that's going to depend on whether its designated target remains stunned. Because you do have the possibility that the target was not stunned, but it got a lucky roll and stunning roar recharged right away.
