Mammoth Lord (Ex)

At 10th level, a mammoth rider becomes immune to the dazed, fatigued, shaken, sickened, staggered, and stunned conditions. If she succeeds at a Fortitude or Will save against an attack that has a reduced effect on a successful save, she instead avoids the effect entirely. If a mammoth rider and her steed both hit an opponent on the same turn, the foe must succeed at a Fortitude save (DC = 10 + half the steed’s Hit Dice + the steed’s Strength modifier) or be stunned for 1 round. Whether or not the target succeeds, it is immune to this ability for 24 hours thereafter.
