What above said.

Legendary tier is not possible from the first magnifying glass reveal. The only way is to use a super miracle cube (whatever it is called). Once legendary rank is reached, only that cube can be used on the item.

you can get epic/unique on first magnifying glass.
btw, can anyone tell me if its possible to get legendary on 1st try too? o:[/quote]
nah, that's why they had to make specific cubes for legendary teir

I think 3L chance is about the same as the Premium Cube chance, which was either 20 or 25%.

You can get epic/unique on first reveal (though less likely, obviously).

From my experience its about 1 in every 5-7 tries. So 15-20%
Note: I've tried about 1000 times =p

wow thanks guys makes me feel better, and when you say you can get epic/unique on first pot, its not possible to go from rare --> unique right?

oh even better news .... thanks a bunch everybody!

if it was revealed to be unique, it means it didnt go from rare -> uniq, it started off being uniq
