Q37: In the Martial Power 2 handbook the fighter power Reaper's Hook says this:

If the target moves before the end of your next turn, it takes extra damage

equal to your Constitution modifier. Weapon: If you're wielding an axe or a pick, you can shift 1

square after the attack. You pull the target to the square you vacated.

Therfore, If i have the weapon required to pull the target, does he take the extra con dmg right away or need to use his move action for it to apply it?
