Bloatsack the Vile round 5:
I have no idea how much cover you get but Bloatsack the Vile again attempts to snipe
Heavy Crossbow Attack! (1d20+10)
/\ If it threatens (1d20+10)
If it hits (1d10+2)
/\ If it crits (1d10+2)
The attack has +2 added in because you can't see me (I think. Otherwise ignore that.)
Edit: DC8 + distance for the spot check. It might not matter though...
