Did you die in the map with an omen active before uploading this clip?

first of all boss is bugged, I closed the game and reopened it hoping it would fix it. Of course it didn't work.
I had to die because the portal couldn't be opened in the arena.
''omen of amelioration'' was active and I died to the boss, but I still lost 10% experience.
