A slurk's back is crusted with thick, dry slime and dozens of nodules. As an action at will, a slurk can squirt a jet of this slime from one of these nodules as a ranged touch attack against any target within 30 feet. Anyone the slurk successfully grapples with or chrages is automatically squirted with back slime. The hardened slime can be removed as a full-round action with a Strength check. The slurk's back slime grants a creature riding it a +8 bonus on checks made to stay in the saddle, but a -8 penalty on checks to dismount.
