Trample (Ex): A titanothere can trample large-size or smaller creatures for 2d6+15 points of damage. Opponents who do not make attacks of opportunity against the baluchitherium can attempt a Reflex save (DC 26, Str based) to halve the damage.

While peaceful, these creatures will defend themselves. They will gore or trample their opponents.
