Rotwood Reaper

If you play or create your first aura of the turn before the damage step of this weapon’s attack, the weapon will get the +2 and will be calculated in the total power of the attack when damage is calculated.

If you play or create your first aura after the attack’s damage step, the weapon will still gain the power; however, you will not retroactively deal damage equal to the power increase since the damage was already dealt.
