Solved There is a problem

I tried the +0 fallen lord's armor 15 times with 70-80 fs and it burned every time.
18% chance that appears on the screen.
There is also the fs event, 20% more effective.

When I try it in enchance simulators on the internet, it is successful at least 1 time, 15 times with 18 chances.

I think there is a problem, please make a review.

Well, it all boils down to RNG, so there's no much I can tell you other than: keep trying!
I know enhancement can be triggering, yesterday I failed a bunch of manos, which we don't even use FS... Now I'm stuck on PRI, which has 20%+ chance to success, but that's not happening, and that's part of the game.
Also, don't forget this tip: avoid doing overstacks to something that won't downgrade lower than the level it's already is.
