Seiretei Challenge

This is a tower mode in which you need to beat all of the stages to get to the end.

The challenge consists of 3 floors in increasing difficulty. Each floor has its own path with multiple stages, each stage presents you with at least 2 options for you to advance and finishes with a boss fight. The possible options for each stage of a floor that are presented are the following:
 * Blue Flag: easy fight. After the fight you will be able to choose a buff(treasure) for your team.
 * Pink Flag: hard fight. After the fight you will be able to choose a buff(treasure) of higher rarity for your team.
 * Healing Pool: Will heal your characters a certain percentage.
 * Shrine: Allows you to revive one of your fallen characters.
 * Recruitment: Lets you recruit a unit (only for seiretei challenge)  from a pool of different options.
 * Shop: Presents you a few offers for components or shards.

Once you reach the end of each floor you are presented with a chest as a reward. You can purchase up to 10 times and the price increases up to 50 jades for each purchase from the 5th chest onwards.

The mode resets every 48h.
