Once per turn, during damage calculation, when another Defense Position monster you control is attacked by an opponent's monster (Quick Effect), you can activate this effect: During that damage calculation, the DEF of your attacked monster becomes equal to this card's DEF, also it cannot be destroyed by that battle.
