Talismans just make no sense to me in general. I hardly understand why they even have gold prices, because you would have to be completely insane to craft or buy one.
Here's the effect of one talisman: "This knot of copper wire reshapes itself in a new pattern every time its affixed weapon deals damage. When you activate the coil, the damaged creature must succeed at a DC 31 Will save or be stunned 1. If it critically fails, it instead becomes stunned 2"
Seems pretty nice to me. Of course, it's high level, all the low level ones are basically small bonuses, but I guess I don't have a problem with having low-level items that aren't very powerful. I can see a logic that says just only list the higher level items, but honestly, I don't think I've ever expected a starting-level consumable to be terribly useful in any game in any system I've run.
