Delving Deeper
Due to the casting time of sleep, Sil's spell doesn't actually go off until the end of the segment, so none of the halflings are asleep when the rest of you act. Since you pretty much all went for the nearest halfling, that means the boss.
Though the halflings were prepared for trouble, your party still manages to react first. Walker fires first, but his arrows go wide, and the rest of you charge the halflings' leader. He's nimble enough to evade most of you, but Lenny and Brian manage three good hits between them. Sil's spell follows shortly after, leaving the leader unaffected but dropping the four henchmen. The leader himself was turning to run even before you engaged, and turns to do so now, but in the process he leaves himself open - and that is enough for Lenny to strike a killing blow.
With the leader dead and the other five halflings asleep, the battle is over almost before it began.
