Hello!
You can complete this mission, but you need to follow this sequence:
1. Equip the necessary artifacts on the champion, which is listed in the description (e.g. attack rare hero for mission 3).
2. Upgrade the artifacts to the level specified in the description. (e.g. +4).
If you equip artifacts that have been already upgraded or use an unsuitable hero, the mission will not be completed.
To: Rebirths Master response, So I have done exactly as the steps say on multiple characters and to my dismay no results were found. I still have the mission at 0 of 2 complete. Also I should add i just had about 500,000 worth of silver and spent near 400,00 on upgrading the base artifacts to 13+. And seeing as everyone else is having the same issue it appears that nothing has been done. So I will show the pictures and once finished with this comment I will be deleting this game and never play it again. I spent 20 bucks so far on the little raid cards for xp very glad that I didnt waste to much money on this trash game. But its very frustrating investing a lot of time on a game i actually enjoyed, only to get stuck by a mission that wont allow you to get free rewards such as silver. To me its like the game said your free trial has ended now go spend your hard earned money on 1’s and 0’s. This game is as my name says, absolute garbage. So to anyone wanting to play this game id avoid it. Youll have a much happier life.
