After an especially debilitating spell in the Cave of the Nadir, I find myself with Dramatic Tension at >3. As far as I recall, the usual uses for this - War of Assassins, Wilmot’s End - just reset the quality to zero even if it’s higher than the required 2 at cash-in; is there anything useful to do with the excess prior to that step, perchance?
Not that I know of, sadly. I think cashing it in will reset the quality as well.
No uses. It’s a bit soul-crushing when you’ve grinded it a bit too far by mistake, but you’re going to have to lose it.
