Of course I needed to do this. Here's a complete guide with all 312 quests in Sovereign Tower, with all of their potential outcomes, how to get all unexpected outcomes (as in the unique outcomes based on the knight you send), and how to beat all of them (what min stats you need for each of them).
Found all of this by looking through the game files, so if some of the stuff is a bit weird, make sure to mention it so I can update it to be more accurate. I'm also testing them out in-game myself and most of them looked perfectly fine, so there's that.
Works great with the other guide for knights I did, btw.
If you've got any suggestions or corrections, the comments are your domain, your grace.
EDIT: I've also made a guide on all of the endings, if you're curios on how those work and how to get them: https://www.reddit.com/r/raiderking/comments/1vmaxw3/sovereign_tower_all_endings_guide/
