Creatures within the emanation area (or those who enter it) sheath or secure their manufactured weapons and can't unsheathe or unsecure them. Each potentially affected creature is allowed a save to avoid the effects when the spell is cast or when the creature first enters the emanation area. Affected creatures are aware of this enchantment. Therefore, they may choose to prepare unarmed attacks, spells or natural weapons. Creatures who leave the area are free to use weapons as they choose, such as ranged weapons.
