Tower

What is the tower?
The tower in million chain is endgame content and a stage of the hardest difficulty possible in million chain, it has varying conditions and requirements that change every month

You must be over rank 20 to enter the tower (And realistically, 100+ with a really good team to clear it),

The requirements and mechanics of tower vary from month to month, and it goes from only allowing certain colors to enter to restricting rarity and only allowing units above or below a certain rarity to enter.

The stamina cost also will vary, some towers are free to enter while others will cost stamina to enter and challenge it.

You will use a special tower team different from your mission team and puzcoli team. The team will consist of 4 units and you cant use friend assists in the tower, you must clear it with your own power.

Once you reach a milestone of X floors cleared in the tower, you will be allowed to choose any unit from your catalog and that unit will be your reward. You cannot choose special collab units but everything outside of that is fair game. The tower will award prizes at milestones that change every month and will be announced in the official twitter or the million chain JP wiki.
