Ah my bad. They released a pet "Nimbus" which is a cloud. On summon it heals you for 150 and puts everything to sleep (that stacks with more clouds). Through this pet you can go infinite dk and essentially solo everything aside from raids.
Hell you can probably solo most raids at this point if you have a high % combo card.
Which is sad because I'm sure they have the source code. RYL/ROW was the first action mmorpg I ever played, it got me into Continent of the Ninth and made me stay far away from target based games. It is what made me who I am today, and seeing it die like that is brutal.
