I'm trying to make a good embroidered craftman's clothes outfit, at least a +3. I burned through 14 outfits I made and all were destroyed by fails. And this was using +60 and +80 Valks. Not one enhancement was below 90% and I only got it to +1 one time. Guess there's a reason they are going for almost 5 billion for a +5?

but Is there a trick to this? Or some tips on how to do it?

Nope, just RNG as usual. Also you really misused these failstacks, that was way above what you should be using to be cost efficient on that.

maybe but I still fail. I suck at enhancing. If I don't use FS that high, I can't get my chance over 90%. Even then, at 90% I mostly fail. It's not bad if the item doesn't get destroyed but if it does, I lose everything I'm gained to that point. Mostly a lose / lose!

90% is the cap for enhancement chance. And whenever you hit it, you know you are overstacking by way way way too much. Enhancement is not nice in this game, it's very punishing. You need to be ready to lose your investment and only enhance when you have the backup items to make it worth
