Battle tower
A new activity where theres a tower with 100 figths, starting from weak monsters all the way to legendarys (kinda like in pvp, but add legendary monsters ) it would have the option to save your progress (incase we have to leave) and continue where we left, also could add a few ONE TIME quest. For example: reach lvl 25, reach lvl 50 and reach lvl 100.
