So in my campaign, I have created three suits of armor. The general idea is that the Gems of Teravast are still the end game, but there are a total of three suits of legendary, god like power. They represent Order (Law), Chaos (Chaotic), and Balance (Neutral) The Balanced is the most powerful, and is powered by the Gems of Teravast. However, the armor that my player came up with is, unknown to them, the armor of Chaos. The armor's major drawback is that, because it is made of dragon bones, the spirits of those dragons are locked within it. The powers the armor grants come from said dragons, but, they are sentient. And they hate the user of the armor's guts. And so every day, the wearer must convince at least one of the dragon spirits inside to help him through role playing and dice rolling. The other draw back is that the power is only activated by putting on the helmet, but the every time the helmet is donned, they must roll a d20. If the roll is 2 or less, the dragons in the armor take control, and they will kill everything in sight until either A) The wearer is dead, B) Someone else manages to remove the helmet, or C) Every living thing in the immediate sight of the wearer is dead.
