yes, i cant upgrade my alt hero mask from purple to orange, i did it for more than ten times in a row, maybe, i will try to put that purple mask to my main hero, and try to upgrade it again, but when it equipped by main hero.

It\'s all RNG guys, 10% is soo small that is why it is so hard.. My hardest one I spent I think around 300 plus to upgrade to supreme. 500 jewel elements failing is painful, but it is normal. Just wishing the best of luck next time you upgrade.
