When Bartlett left the basement, his Space Ring contained several oddly-shaped potions and a sheepskin paper explaining their effects.

Rest assured, these potions are basically complete, having distilled my countless experiences, and I believe they should be of help to you," said Alchemist Joriel at the time, "I know I'm not a good person, and I don't deny it. Because in this Multiverse, good people cannot achieve great things."
