Note:
With both a Thief die and a Highlander die, your Thief die can roll infinitely as long as you have the Highlander die in your pool.
You can play around Neurotic by placing the die inside a building without activating it (such as a house / Cookhouse without food) while you roll the other dice and then pick it back afterwards when you need it
