Evasive Strike

Melee attack
At-Will
Target: 
One enemy
Attack: 
Dexterity + Level vs. AC
Hit: 
WEAPON + Dexterity damage, and you can pop free from the target.
Miss: 
Damage equal to your level.
Adventurer Feat: 

If you drop the target with your evasive strike attack, you can pop free from all enemies instead.

Champion Feat: 

If you hit with evasive strike and the natural attack roll was even, you gain a +2 bonus to AC and PD against the next attack that targets you this battle (no joy if it's an attack vs. MD).

Epic Feat: 

Ok. Thanks to your slippery mind, the champion feat benefit also provides a +2 bonus to MD.
