Soaring Raptor Strike

Tiger Claw (Strike)
Level: Swordsage 3, Warblade 3
Initiation Action: 1 Standard Action
Range: Melee Attack
Target: One Creature

You leap into the air, catching a larger opponent by surprise as you jump over its defenses to plunge your weapon into the crown of its head.

Make a jump check with a DC equal to the target's AC. If it succeeds, you deal an extra 6d6 damage on your attack, and attack with a +4 bonus. If it fails, you do not attack.
This must be used on a creature larger than you are.
