Clarify its effect to me cause currently the way its effect is used makes no sense. ATTACKS gains DEF until the end of the damage step. Like what even. If its being the aggressor shouldn't it be gaining attack as well?

When Unrelenting attacks a monster, that attack target's ATK and DEF become Unrelenting's current DEF, but at the cost of not being able to destroy the attack target by battle.

Example, Unrelenting attacks a Blue-Eyes White Dragon. Blue-Eyes' ATK and DEF become 1600 for the duration of the battle, and the opponent would take 400 damage. However, Blue-Eyes is not destroyed.
