For Magi Summon, you need to spend 15 Gems or 150 Gems to draw a Magi at random.
You can insert Magi into your equipment and obtain skills that you can use in the hunt, provided that your Magi gauge is full.
To summon a Magi into your possession, follow these steps:
1. Tap the circle icon and go to "Summon".
2. Tap "To Magi".
3. Use 15 Gems to summon one random Magi or 150 Gems to summon 11 random Magi.
You can insert the Magi you have received into your equipment as long as your equipment has a compatible Magi slot.
