Cape of the Mountebank Level 5+ Uncommon
Power (Teleportation) Daily (Immediate Reaction)
Use this power when you are hit by an attack. Teleport 5 squares and gain combat advantage against the attacker until the end of your next turn.
Do you think "reaction" is intended, so you take damage from hit, and then teleport, or is it "a case of mistaken interrupt", like with Parrying Weapon's ability? (here - What is the timing of Parrying Weapon's ability? )
So, how should I rule, damage or no damage?
