Target 1 face-up monster on the field; equip this card to that target. It gains 300 ATK and DEF. If it attacks, it gains ATK equal to half the ATK of the attack target, during damage calculation only.
A monster that equips this card will rarely be beaten in a battle.
Recommended to activate during enemy turn for the surprise 300 attack increase if it can destroy enemy monster. This will leave them open for a direct attack instead of going for the attack increase when attacking a monster.
