A doubt about The Alchemist

[Wanderer]

Hello,
I understood from some other thread that you get the alchemist after completing 6 times the sacrifice "wheel", so you receive 25 fragments every time, to complete the 150 fragments and have the soul.

Well I completed the wheel 3 times, all correct, with 25 fragments, in the fourth time I only got 20 fragments, and now I have 90 fragments, so I need more than 6 times to have the alchemist? Was it changed recently?!

It's not changed, you get 15-25 fragments (maybe 10-25, not sure) on each vortex. How many times you have to go around depends on your luck.

its random. Im not sure I have EVER gotten 25 frags from a vortex, so congrats on 3 in a row.

Some time ago I was almost sure that I finished it more than 3 times, but I thought it was my mistake and I forgot about it... So I think the first two times it gave me 10 + 15 or so, and I have finished it more than 3 times. Thank you!
