You can jump off willing allies and unwilling opponents to attack creatures from above.
Benefit(s): While using Dragonfly Style, the bonus on your melee attacks increases to +2 and applies to opponents up to two size categories larger than you. In addition, you can substitute a creature your size or larger in place of a vertical surface. You can freely use a willing creature in such a manner, but using a hostile creature requires a successful Acrobatics check with a DC equal to the creature’s CMD. If you fail this check by 5 or more, you provoke an attack of opportunity from the hostile creature.
