Acme_Magic_Bag

This magic bag has a boatload of anvils. If you take out an anvil for an action, the anvil will fly up fifty feet. The next turn, the anvil will fall on the nearest enemy, auto hitting and requiring the enemy to make a DC 19 Strength saving throw, taking 5d12, or half on a successful save.

Notes: Requires attunement by watching Acme cartoons for 12 non-stop while holding the bag.
