Card Rulings:Roaring Earth
- It targets 1 monster on your opponent controls. Also, a monster that has been determined to be destroyed by battle cannot be targeted by this effect.
- The effect to decrease a monster's ATK/DEF by 500 applies as long as the target remains face-up on the field.
- When battle damage is inflicted, the effect of each "Roaring Earth" that is face-up on the field will be activated.
- Even if a face-up "Roaring Earth" is no longer on the field, the ATK/DEF decrease is still applied.
