Attack rolls: 17+3=20 (vs. Lorien) [hit], Damage >> 9+2=11; 10+3=13 (vs. Phar) [miss]; 13+3=16 (vs. Quinn) [miss]; 9+3=12 (vs. Caerth) | Aureus is hidden, so no attack vs. her.
Attack roll (w/screaming bolt): 12+3=15 (vs. Lorien) [miss]. Aureus, Lorien, Phar, and Quinn must make Will saves since they are all considered to be within 20 feet of the path of the bolt. (Caerth is far enough back from the shot that he doesn't need to save.) The DC is 14. On a failed save, a character becomes shaken (PHB, p. 312) for 5 minutes.
Since Lorien cast a spell that required a verbal component, he had to stop singing. However, his inspire courage (+1 moral bonus vs fear effects and +1 morale bonus to attack and damage rolls) lasts another 5 rounds. The bonus applies vs the screaming bolt. Also, for those PCs with wax in their ears, I believe I gave a +2 circumstance bonus vs. sound attacks. It probably should only be +1, but I think I already stated +2.
Lorien's save: 6 + 4 + 1 (inspire) +2 (wax in ears) = 13 (failed)
