Chamber of Challenges
A new feature
will become available
after maintenance on July 18th!
Introducing the Chamber of Challenges
Within the Chamber of Challenges, the boss awaits! Challenge the
boss in five different difficulties - INT, ADV, PRO, ELT, and LGD.
Clearing the missions will yield a new item,
red star quartz!
* Once the mission is cleared, clearing the same mission will not
award any more red star quartz.
Red star quartz is an item used to exchange for new enhancement
units, called doors!
Doors can be used to further increase the max limit of a unit's
- Using a mini soul door,
Sacred Shield Charlotte's SPR limit will
increase by 1 from 65 to 66!
- Using a soul door,
Sacred Shield Charlotte's SPR limit will increase
by 5 from 65 to 70!
You can fuse multiple doors to your units to increase each
parameter's limit up to 1.5 times the original value.
For example: Sacred Shield Charlotte's SPR limit can be increased up
to 97, deriving from 65 x 1.5 = 97.5 (Digits following the decimal
point will not be included in the maximum value)
Exchange red star quartz for doors by accessing the banner inside
the Chamber of Challenges!
The boss will not stay in the Chamber of Challenges for long! The
boss challenge will remain for a week before a new boss challenge
takes its place on maintenance day.
Once the new boss challenge begins, the missions will be reset, and
clearing them will award red star quartz again.
* The boss and its contents may be subjected to change.
