Volo's Snatch

Using a bonus action, the caster of this spell can reach out towards an item within sight and make the item fling itself towards their hand. If the item is larger or heavier than the caster is able to lift with one hand, the spell fails. 

The spell can not break loose items that are solidly secured by chains, rings, hasps, etc. Likewise, it can not be used to take an item that another creature is holding onto or wearing.
