Then it's called "Altar of Blood". A game mode that is also dying at High Speed by the way, to the point that some players will never be able to try it. Never been able to launch one personally, but it was very entertaining to see a queue timer doing circles for hours while doing something else. My guess about Savage Rift is that some of their devs played too much Tower Defense on their phones instead of actually working. Since they don't have that much more consideration for their work and game than for the first basic mobile product, they must have thought that it would be a good idea for BDO. Of course it was not, and with no surprise it did fail, badly.
