[New World Record] Bera GMS Zakum speed run 1:48.70

When you're sealed, you'll see numbers on your screen, but others will see misses as you attack, until the symbol appears over your head. You don't actually do any damage. This is most apparent if you train at guardians, or watch someone train at guardians and you see random misses.

I can always "feel" when I'm sealed at Zakum, character just responds a bit differently. Don't need to wait for the status to come up. Darkness on the other hand is hard to tell.
