Gorebrute Elite

( Races of Eberron, p. 114)

[Shifter]

Your mighty charge attack can knock down foes.

Prerequisite

Shifter with the gorebrute trait,

Benefit

Any creature that takes damage from your horns during your charge attack must succeed on an opposed Strength check (you gain a +2 bonus for charging) or be knocked prone in its space. The defending creature gains a +4 bonus on its check if it has more than two legs or has some form of exceptionally stability (such as a dwarf's). A creature that can't be tripped also can't be knocked down with this feat.
