* If a monster was determined to be destroyed by the battle during damage calculation, send it to the Graveyard first.

* Then effects that activate when a monster is destroyed by battle and sent to the Graveyard, activate now.

* Then if all effects activates/resolves and you would end the Damage Step, effects that apply "until the end of the Damage Step" disappear

* After the end of the Damage Step, return to the Battle Step. If the turn player does not want to attack again after that, go to the End Step.
