Living catapults are normally set up to attack foes from afar but when enemies get too close, they attempt to run them down or smash them.

Launch Boulder (Ex): As a standard action, a living catapult can pick up a boulder weighing 60 to 80 pounds (Medium-size object) with its launching arm and hurl it as a ranged weapon with a 200-foot range increment.

Trample (Ex): As a standard action during its turn each round, the creature can literally run over an opponent at least one size category smaller than itself. The trample deals 3d12+5 bludgeoning damage. A trampled opponent can either attempt attacks of opportunity at a -4 penalty or make a Reflex save (DC 28) for half damage.

Construct: Immune to mind-influencing effects, poison, disease, and similar effects. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.

Magic Immunity (Ex): Living catapults completely resist most magical and supernatural effects, except as follows: Warp wood or wood shape spells cause 2d8 points of damage and hold the living catapult immobile for 1 round. Fire effects cause damage normally.
