Well I was just grinding a Arcade level when I came up with this weird idea. It's a new daily mission called Abyss Arena, it will be an endless series of arenas with no help and no healing pads.
Mission Rules & Mechanics:
-You can either go Solo mode or a Party of 2 - 4 members
-No loot will dropped by monsters (excluding Health Pills, Antidotes, Boosts etc.)
-Each time you clear an Arena you may leave or continue at the Lift
-If you're ever defeated in combat, you will get NOTHING.
