While subject to this spell, any time you are dealt damage, your attacker must roll damage for the attack twice and take the higher roll, but the attacker must also succeed at a Will saving throw or become demoralized for 1 round. Each time you deal damage to a creature demoralized by this spell, you roll damage twice and take the higher result.
