Specifically, the patch introduces the Automaton Assault event dungeon through May 2nd, pitting players against Hongsil’s maddened creation, Princess Bloodlust. There’s also an associated limited-time jackpot with a new outfit in the mix, so you’ll have even more reason to throw in your lot against the crazy robot.
Other features of the patch? Well, if you really aren’t sufficiently delighted by fighting a giant robot named “Princess Bloodlust” for some reason, daily challenge quests have been updated and Chromatic Thread is now bind-to-account. But the main focus, as mentioned, is fighting a giant robot. That’s a good thing.
