Does Duggins get his spell up before we get to act?
If not - BR 12 and 15 on him, two arrows, for (BR 4 and 5) 11 points. Perhaps disrupting that spell. Then I cast sleep on the guards. Ha!
If so, first I cast sleep on the opponents, then I go for some shootin'. BR 5 means I don't see Duggins as a threat, so:
If there are three or more enemies (Duggins is NOT one of them for me) I do some more shootin' at the biggest and baddest. See the BRs above, I guess.
If there are two or fewer enemies, I try and free the prince. "Medic!" Perhaps we could get the bonnie Prince some CLWing while I try and get him out of this contraption?
