Hi,

I have a problem with a mission presented at the picture below ("Equip 2 Champions with 6 Artifacts of Level 12 or Higher").

=> I have upgraded all artifacts to level 12 (6 artifacts for each Champion) 

=> I have equipped 2 Epic Champions with those artifacts

=> challenge was not achived

=> I've removed all those artifacts from 2 Epic Champions and put them again on those champions

=> still challenge was not achived

=> there is no info about additional conditions after clicking on that mission (so no info that artifact should have specific substat or something)

Would you mind to give me some hints how to pass this mission? 

Thank you in advance for help.
