Tutorial/Electrograna...

These miraculous spirits are called Electrograna. They spawn from the branches of the Thunder Sakura and grant the protection of Electro.

Electrograna have various powers. Carry them with you to travel rapidly using Thunder Spheres, traverse Thunder Barriers, and even withstand Balethunder.

You can offer Electro Sigils to the Sacred Sakura at the Grand Narukami Shrine to enhance Electrogranum strength.
Strengthened Electrograna will even aid Travelers they connect with in fighting against their foes.
