Earth Child Topple (Combat)
Your mastery of balance and momentum allows you to bring down giants with your bare hands.
Benefit: You can trip a creature of the giant subtype of up to Huge size. While using Earth Child Style, you add your Wisdom bonus on combat maneuver checks made to trip a creature of the giant subtype, as well as on attack rolls to confirm a critical hit against such a creature.
Normal: You can trip only those opponents that are one size category larger than you.
