Plow Through (Yellow)

The first part of the card only affects your next weapon attack and the “if this weapon is defended by an attack action it gains +1 until end of turn” does not affect or stay on the weapon after you have attacked with it.

The second part of the effect (If this weapon is defended by an attack action card) stays until end of turn as it gives the weapon +1 so if the weapon was to attack again it would still have it’s +1. Note: That if it is defended again by another attack action card it would not gain an additional +1 as that effect was only to the weapon attack.
