We cover a lot of World Firsts here (and the guild gets their fair share of them as well), so it seems only right to congratulate a fellow insanely dedicated player.
Cerli from The Brigade on The Maelstrom has maxed out his Unholy artifact, getting 54 traits completed and spending 65 million Artifact power in the process! That takes a LOT of mythic pluses, over 2000 in fact, with 818 Maw of Souls, 383 Darkheart Thicket and 444 Court of Stars clears, in addition to way less clears of the other dungeons - and that's only the ones he finished in time!
