Chameleon Attack 20Deadly Duplication

Your skill at imitation has culminated in the ability to duplicate even the most complex attacks.

Standard Action      Personal

Requirement: You must use this power at the end of an extended rest.

Effect: Until the end of your next extended rest, you can use an ally’s daily or paragon path attack power of 20th level or lower as if it were your paragon path daily attack power. The ally whose power you gain must be present during the entire extended rest before you use this power. You can use your Charisma for the attack roll and damage roll instead of the ability scores normally associated with that power’s attack rolls and damage rolls. You do not need to meet the normal prerequisites to use the power, but you must meet any of its requirements.
