Combat

Dune reapers prefer to lie in wait for their foes, hiding behind or atop sand dunes until their prey draws near. Once a fight starts, they're straightforward combatants, but they're smart enough to use basic tactics like flanking and concentrating on wounded enemies.

Improved Grab (Ex): To use this ability, a dune reaper must hit with its mandible attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity.

Rend (Ex): A dune reaper that establishes a hold with a successful grapple check latches onto the opponent's body and tears the flesh. This attack automatically deals 2d8+50 points of damage.

Skills: Dune reapers have a +5 racial bonus on Jump checks due to their powerful leg muscles.

Dune Reaper Drones

Drones comprise about two-thirds of all dune reapers. What they lack in intellect they make up for in perseverance and ferocity.

Drones can smell which of their fellow dune reapers are warriors, and receive orders from them in a subtle olfactory language.

Drones are aggressive, territorial combatants that use ambushes, flanking, and other rudimentary combat tactics to good effect. They cooperate with each other better when a warrior leads them into battle - without the warrior, their attacks tend to be unfocused, but no less ferocious.
