With the ongoing 20% affix event going on until NGS launch I would assume that means anything 80%+ is actually 100% (since that 80% was 80% prior to the event starting I have to assume it's just in the background)
However, in upslotting my new units I had it fail several times even at 80%. So what's the deal? Is it broken atm? Or does the 20% only apply to normal affixing and go away when trying to upslot?
