Seems we are in agreement - for consumables in general.shrugs I mean yeah, potency crystal is most commonly used ones, rest of them tend to be more like "Oh, neat, found this, I guess I might as well use it or never bother(puts it into same pile as 50+ cure moderate wounds potions)"(I'm not joking about that, we had hundreds of cure moderate wounds at high level 1e pathfinder just from enemy equipment). Which is my usual experience with consumables in first place, people only buy them if they are bored of saving money or do specifically know they need it or know what kind of success they want to maximize
I guess I just take Talisman design more personally than you. I'm insulted by the designer asking me to jump through all these hoops, and for what? To gain a ridiculously restricted and minimal ability for the shortest possible time imaginable? Let me give you my detached and professional opinion: Fuck, no!
50+ cure moderate wounds potions come off as positively generous design work compared to Talismans!
