Bag of Bones (OP)

This pouch is full of assorted bones from humanoids. 

As an action you can pull a single bone from the bag and throw it to an unoccupied space within 10 feet and and the command word "Transform" is given. At the end of your turn the bone shatters and summons an undead creature.  The bones change into 2d8 +4 skeleton which use the below stat block and are under your control. The level of the skeleton goes up with the casters level. The Skeleton will always be two levels below the caster. (except at level one and two, which would be the starting skeleton stats)

Skeleton AC12 base. Armor can be added. (ie shield +2 AC or other armor +x AC) HP 2d8 + 4. goes up with casters level. SPD 30 ft.

You can give the skeleton verbal commands and it will follow them to the best of its ability though only noncomplex commands can be issued such as attack a target, guard a creature or object, fetch an item, assist an ally, and similarly simple commands.

The undead creature summoned by this effect is friendly to you and your companions. In combat, the undead creature shares your initiative count, but it takes its turn immediately after yours. It obeys your verbal commands (no action required by you). If you don’t issue any commands, it attacks the nearest hostile creature. The undead creature becomes a pile of broken bone shards after 4 hour or when the undead creature summoned drops to 0 hit points. (Any items you placed on the summoned skeleton turns to dust when Undead Creature becomes a pile of broken bone shards.) Once used, the bag cannot be used again until a short or long rest.

Notes: Required Attunement. (Requires 15 Charisma)
