The Endless Tower runs in Ragnarok X: The Next Generation can be done daily with the one-time purchase of the key per day. We try to improve our finish in each attempt by having the ideal party members do each of their roles in every monster mob battle and also on the MVPs. That is to remember each of their attacks and skills and how to avoid them. I also get to learn stuff like the items and skills to consider after reaching Floor 21. That is the HP% regen passive skill that will bypass the Deviling penalty.
