Standard move to follow Wren by moving towards the north tunnel I believe.
If he can then see the splatterman but at a distance then casts disrupt undead. To hit: (1d20+7)[20] damage: (1d6)[2]
If he ends up next to splatterman then uses cure light wounds on splatterman. To hit: (1d20+7)[9] damage(1d8+1)[7]
