I levelled up during duel of truth to 22 so it messed up the quest. I completed the boss and won the fight with almost 8000 damage done. Quest completed the second part but not the first so i couldnt claim anything.

I'm now missing 1350 valor, 1125 exp and 25 hero of empire rep along with 1 x Dragon Breath lesser phial.

This really should've been fixed by now so everyone can get the rewards they earn.
