After reading other comments I was surprised. I wondered if auto_sklearn gave such bad estimates because I encoded categorical features myself in a way which is not very suitable for it. I wanted to see if I can tinker with it to get it to give me a better answer. I let it choose how to encode categorical features on its own. I got a better mean absolute error and got predictions, which are very different for Hammer of Capability, Pendant of Truth, Ring of Joy, Pendant of Hope:

With these new predictions, I think I can buy Pendant of Hope, Hammer of Capability, Amulet of Wounding, Pendant of Joy, and Pendant of Truth to get approximately 154.83 mana for 181 gold. That’s what I do. Although I understand that this is cheating, since I’ve seen other people’s answers.
