9 0 2You need to synthesize 20 things. You can synthesize later on in the early part of the game at the general stores.Note: Don't synthesize more than 1 thing at a time or it will glitch the achievement.Showing both comments.

I ask because I had 50 hours invested before realizing that my synthesis achievement is glitched.Posted by Dingo Salad on 01 Oct 12 at 09:59 I think you should be fine. I got this achievement and not the one for synthesizing one item, oddly enough, and they're on separate saves. I imagine your Xbox only cares that you get all the achievements, considering it's probably impossible to get every single one on one run-through.Posted by SoulPerception on 25 Jun 13 at 00:18 Leave a comment
