Blue Practice Robot

A mechanical weapon that lay dormant in the depths of a cave. It seems to have been created for the purpose of combat training, as it will not kill its opponents even after it has battered them senseless. It can instantly read its opponents and adjust itself to match their weaknesses. It can do this with any opponent no matter their build, magic capabilities, or even any latent abilities they may possess. Its self-repair capabilities are no less formidable—so long as its core is intact, it can repair and rebuild any amount of damage in a matter of hours after the battle is over.
