Combat

A gray render attacks to kill whether to bring down prey or to protect itself or those it has adopted. When hunting, it sometimes attempts to hide and wait for prey to wander close.

Improved Grab (Ex): To use this ability, the gray render must hit with its bite attack.

Rend (Ex): A gray render that gets a hold latches onto the opponent's body and tears the flesh. This attack automatically deals 3d6+9 points of damage.

Skills: Gray renders receive a +4 racial bonus to Spot checks due to their six keen eyes.
