Hi, I urgently need your help in carrying out this mission. 

The name of the mission is: Artifact Mission: Equip an ATK type Champion with Gauntlets, Chestplate, and Boots with ATK (%) as their primary stats. 

I've been trying to work her out for over two days, I still have no idea how to do it. I don't even know why I'm 1 / 3 satisfied. I'll be grateful for any advice. THANKS!

Same as this waisted 2 days trying this will not move past 2/3 i will just move on and hope for a fix soon

Could you shaRe with us some screenshot? 

Nothing to screenshot, I know that others have gotten hung up on this. It's in Artifact Missions. You get your 2 atk champions and kit them out with the required items (ATK stat gauntlet, chestplate, boot raised to lvl 12) and then you don't get the award and you're stuck in artifact missions and can't get any further awards.

I reported this at least a week ago and I'm still stuck on it, it hasn't been fixed in my account. Looking for a support email to report it again. Maybe the mission is worded wrong.
