When an attack is declared involving a monster you control and an opponent’s monster: Pay half your Life Points, then target 1 face-up monster you control; until your opponent’s End Phase, that monster gains ATK equal to the difference between your Life Points and 4000. You must have less than 4000 Life Points to activate and to resolve this effect. You can only activate 1 'Soul Strike' per turn.
