You need 3 to use in the slots in the capital (go to the same place where you can get keys and accept challenges). The slots can give you as follows:

1. SHS Units such as Frogs, Imps, Gods/Crystals, etc.

2. Raid Items

3. More Brave Medals!

4. Spheres, including some that, while not particularly useful on their own, can be used to craft better spheres such as the Malice/Buffer Jewels or Occult Treasure (all 3 of which are special challenges)
