Chisel of Awakening

Awaken Statue. This chisel can hold one charge. You can use an action to touch a statue of a humanoid of medium size with it and speak a command word to expend the charge. When you do, the statue instantly transforms into a Flesh Golem loyal to you. The Flesh Golem is friendly to you and your companions, and it acts directly after your turn. You can use a bonus action to command how it moves and what action it takes on its next turn, or give it general orders, such as to attack your enemies. In the absence of such orders, the Flesh Golem does nothing. The Flesh Golem reverts to its statue form after 12 hours. The chisel regains its charge after 24 hours.
  Stone Embrace (Curse). After you expend the charge, roll a d100 at the end of your turn. On a roll of 1-74, nothing happens. On a roll of 75-94, the chisel shatters, becoming useless. On a roll of 95-100, the chisel shatters and you must make a Constitution saving throw. The saving throw DC is 15, increasing by 1 each time you use Awaken Statue beyond the first. On a failed save, you take 3d8 Necrotic damage and become Petrified.
