Whenever you cause a creature to take falling damage, they instead suffer 2 damage for every 1 space fallen, ignoring armor.

(1/turn) When you hit with an unarmed strike, you may suffer 1 wound to launch your target STR spaces straight up and make them fall Prone immediately.

You gain a flying speed while using Windstep (you fall at the end of your turn, or immediately if you use another move action, creatures you are grappling also fall with you).

You ignore falling damage provided you are conscious and unrestrained.

Creatures you are grappling can be carried vertically without penalty.

When you fall from 4 spaces or above, you may expend up to STR hit dice (rolling them). Enemies within Reach 2 of where you land take that much bludgeoning damage.

You may use Windstep a second time each turn. Whenever you use Skyward Strike, instead of making your target fall Prone, you may launch yourself to the same height, and Grapple your target automatically, regardless of size (fall at the end of your turn).
