Please I need help to find the name of this mmo.

[eyptr]

The game was basically Crawl but in a MMO, a 4 player coop that did missions and dungeons and a player controlling a wisp that activates traps and becomes monsters.the players could level-up and equip new skills and the ''wisp'' could too, there is multiple choices of type of wisps and hero classes for players. I saw it in a video a while back and I just cannot freaking find it anymore and I don't remember the name, PLZ HALP
