I've spent a bit time on this but dropped it. The amount of time this investigation requires is not worth it in fact on every second patch or so I have to start from scratch.
Aww ok. You got any suggestions on how it can be done anyway? Save game editing?
I second the requests for new features for Rarity level and Reforge level.
Rarity level goes up one level every time you reach a checkpoint, aka Vortex. This keeps going until you die.
The reforge is a crafting option where you destroy a spell part to fillup a circle. once it is full you get a new spell part with a chance at a legendary or something.
I've figured out the forge level. There are two values. One address ranges between 0 and 100, 100 meaning the forge level is full. The other one is either 0 (if first address <100) or 200 (if first adress =100). e.g.
0F8EBD20 = 100
0F8EBD22 = 200 (my current addresses)
I locked those values and now I get a legendary EVERY time I forge an item
Hope this helps.
