Having trouble skilling up Alchemy

[Kaeviathan]

I'm currently level 98 on Alchemy and was trying to skill up with Mamushito (level 91). I crafted around 20 Mamushito with the Kitron Macaroon + Ionis, but I haven't gotten any skill up. Am I doing something wrong?

It seems pretty unlucky to not get at least a 0.1 from 20 synths, I can't help much as I did alchemy before all the changes and was stuck with Sun Waters to 100, just keep at it is all I can say, one thing I always did was only craft on Darksday or the element of the day strong against the crystal I'm crafting with, in your case it would be Lightningday. There are stats to back up an increased skill up + HQ rate on those days.

Sounds like some bad luck. My rule of thumb for the past few levels has been 48 synths to get a full point of skill-up (I'm at 106 alchemy). I always use kitron macarons, both of the crafting rings, and ionis.
