Index -> Glossary -> Permanently

A card changed by an effect that uses the word "permanently" keeps its change even if the card that affected it leaves play. A card changed by an effect that uses the word "permanently" loses its change when that card itself leaves play.

For example: Rebel High General says, "At the end of your turn, all your other units at this unit's quest permanently get +1 attack and +1 defense. " A Rebel Heavy Trooper at the same quest (2 attack and 2 defense) becomes 3 attack and 3 defense at the end of your turn. When the High General is destroyed during your opponent's turn, the Heavy Trooper remains at 3 attack and 3 defense. During your turn, the Heavy Trooper is destroyed. When it leaves play, the Heavy Trooper loses its extra attack and defense.
