Alzar choose the…right (random). He summons a Vrock to help the team as they explore.
Vrock – 60 hp, AC - -2, 2d6+6 damage from one claw, two attacks per turn, it can cast Mirror Image/day, THAC0 12
It can fly with us and move with s, and weighs 500 pounds, so it’s not likely to blow off course due ot the nasty winds.
