Feel free to comment on mine or add your own.
Considering lockpicking is mostly worthless plus picks are cheap enough, I don't think anyone would spend a talent on Jailbreaker.
Mind Over Matter seems like a solid enough and fun one.
Simulacrum seems
way overpowered. I believe you could almost never die with smart use of it. I like the idea of a talent focused on summons though. Perhaps something simple like summons get double leadership bonus from the character that summons them.
For Walking Almanac I'd also give a small crit bonus for your party(understanding enemy anatomy and whatnot).
Walking almanac. i'd suggest a perception prerequisite on it like maybe 10 perception? or 8.
Seems like a good way to ensure the talent never gets taken.
