There are too many variables involved, and they all have different weighs for different players, so I find it really hard to calculate. While it’s easy to compare 3 Runic Yellow with 5 Runic Yellow, how do you compare 3 Runic Yellow with 40 Red Minor, and these with 1 Arcane Forest? How do you compare all that with souls?
That said, the closest tool that I’ve seen to what I think you want is ToDo Monitor
