Base power is the printed value on a card. (Located at the bottom left corner of a card.)

Putting a card into your hero’s soul does not count as charging. Only playing a card with the keyword charge and placing a card into your hero’s soul this way counts as charging.

All attacks you control gain +1 while defended by an attack action card. (This includes your weapon attacks)

If the attack no longer has greater than it’s base power when the ability resolves, it will not gain go again.

You may use the second ability more than once per turn as it is not a Once per turn ability. You may also target the same attack more than once. Multiple instances of go again do not grant more than one action point.

If the second ability has resolved, then the attack no longer has greater than it’s base power, it will still have go again as it has already gained go again.
