"Dungeons" means the Potion Keeps and Bosses, everything on that screen. Now obviously, you cannot gain Artifacts or Accessories in the Potion Keeps or the Minotaur, so just run Dragon or Spider a few times and you should complete that quest. Although getting Shards from completing them doesn't count.

By now the game is so complicated and confusing that for a new person, I do not see how anybody can figure out what is required from the outset. By now I know that artifacts/accessories are those things that fit in the 9 slots under the Icon for Champions/ Artifacts, which also includes the accessories but does not say it up front.  Only four sections under the dungeon tab will meet the conditions to satisfy the quest.

I'm saying this without offense, so if you open any "dungeon" inside the "Dungeons" tab, you can see on the left what are the possible drops from that dungeon. It literally says "Artifact drops", "Porion drops", "Mastery scroll drops", "Accessory drops". So even if you don't know, which is expected from a player who never played the game before, in my opinion you can pretty easily tell what can you get from whoch dungeons. So, I think people just need to be able to read those

I promise you, if you ever win an artifact on the mino, keeps, tt, etc., they will count.  Everything under the dungeons tab is a dungeon.  Just check your aura.

You think that's confusing? Dungeon Divers event will count artifacts you get from Campaign runs but not dungeon runs in the potion keeps, mino, IT, or sandbox. 

You'll get used to it, it's a part of learning the game. 

Yeah, but even that says "Get Artifacts". So immediately Mino, Potion Keeps, and Sand Devil are eliminated. 

I get that, but I can see how it would confuse the **** out of players when an event called Dungeon Divers has to do with artifacts and not dungeons per se. Call it "Artifact Hunters" or something lol
