If this is for the artifact challenges, any Atk champ will do. 

Only Gauntlets, Chestplates, and Boots can have Atk % as their Main stat btw, so you don't need to worry about the Weapon, Helm, and Shield slots. 

i have tried it with,ones all with hp,and with def, but with no luck, what  the atk%, look like?

Use the filter on artifacts to show only the Gauntlets, Chestplates, and Boots, and also to filter out those with atk% as primary.

If you only have very weak artifacts that would fit the description, you can put them on food - just make sure you pick the correct type of champion. You don't have to fill the other spaces and you can remove/destroy the artifacts after the challenge is complete.

Is it a "Bug or Glitch"?  Equip an atk type champion with gauntlets, breastplate and boots with atk as their primary stat?  I have done this numerous times with champions with NO quest complete in sight!?  Please fix this!?

Can you please take a screenshot of the specific quest and gearing?

I'm going to try removing the weapons and helm as "Lexzy" suggested see if that makes a difference.

Ideally we need to see the exact wording in a screenshot of the quest you are on and then main stat of the items.

At a glance you have atk set items in those slots but is the main upgradable stat on those items correct with the quest? Remembering that atk and atk% are different primary stats in this context.

This is not an artifact set you would prolly actually use in the game, like atk% boots.  So it is all a matter of just following instructions to the letter.  You prolly also would not want to pay to remove those artifacts so most likely consider the final product as food. Azure is prolly not someone to just throw away, you can use any common or uncommon atk champ.

Use your filter to search; highlight gloves, chest, boots, and atk% as primary stat. They do not have to be in the same set, like offense or accuracy.
