Affixing issue - Missing 10%

Hello! So I am doing something wrong and I need some help. I'm trying to get an elder reverie on a weapon. When I did this before it gave me 60% change of success when I did it previously but now I'm only getting 50% chance both with 3 copies of it. - I investigated and I may have to enhance them to a certain level?

Thanks for any help!

we had a 'affix boost' event going on right before episode 6 dropped -> increase affix chances by 10%. It's over now. No idea when they are doing this again.

So its normal for reverie to be at 50%? Isnt there another way to get the percentages better?


@FRZA45 3x Elder Reverie + 1x Historia Soul or Fabula Soul will make it 70%
