I remembered Justin said he would not be around much for the next week or so, so went ahead and rolled attacks for him. The attentive may note that Billy rolled 0 for damage because of his negative Strength modifier. Successful hits always do at least one point of damage, even if your strength modifier would make it zero or negative.
You made short work of those! All 20 still standing (Billy barely). Everyone gets 2 XP. What next?
