About the Black Star potion...

When using it to cube in RA can you jump from Rare to Unique pot?

It has zero effect on cubes. It lets you get higher tier stuff when opening ra boxes.

The variables associated with the pot are grade = 3 and dropRIncrease = 5. Logically, I would assume this means it increases the drop rate of grade 3 items (unqiue) by 5%, so it probably doesn't affect boxes (they aren't drops... maybe?)

So then it works on cRA drops?

That's a lot better than what i thought it did...

I guess, but a 5% increase seems really negligible considering the drop rate on unique equips in the first place, but I guess it's better than nothing.

Depends if it's multiplicative or additive.
