Bag of watchamacallit

A simple bag of Watchamacallit, usually contains about 5 charges. However during a long rest if the bag still holds 5 charges you can spend 1 hour of your long rest to turn these 5 charges into 1 mega charge and gain back 5 charges.

1 charge of watchamacallit can create an exact replica of an item, weight, look, smell, and even feels, the clay takes on the form for 1h before turning into ash.

1 charge can create an item of 1ft by 1ft, every charge over gives it 1ft more.

1 Mega charge allows you to create a small construct, that can move, and grab things for you, it can't talk, or take action itself, you need to communicate with it telepathically.
