You’ll note I didn’t say “All” in the title. 🙂 This post is a link to a google workbook that has a sheet that has all of the Thaumaturge endings I’ve been able to find so far, their prerequisites, and basically how I got each one. I know I don’t have them all, and it’s possible I’m unaware of a requirement and just got lucky, but if you know of others and can share the steps – pride level, how earlier quests were handled, etc., I’ll gladly confirm and credit you for the entry. This way we can have a complete-ish compiled list of endings.
Google workbook is here.
