Dead Weight

You alter the perceived weight of a single inanimate object up to 5 square feet in size. For 4 days or until dispelled, Creatures attempting to move the object must succeed a DC equal to your spell save +5 Strength check, on a success the item is moved up to 10 feet. The actual weight is not changed allowing it to rest on whatever surface it normally could

When you cast this spell, you can designate a password or set of conditions under which the object can be moved normally. A creature who speaks the password or meets the conditions does not need to pass the required Strength check before moving the object.
