Magic Battery

The Mana Battery system is the main magic type for the people of Eternus.

Description
The average Eternites have a single mana battery and can reach a second battery, allowing them into the Council of Heroes. Heroes can train their way up to four batteries.

Each time they move up a level their strength increases, their energy is partially restored, and more skills are unlocked. The transition to the third battery involves a golden chinese dragon circling their body as their power is released. The fourth battery is obtained by forming a connection and training with a Spirit and usually some aspect of that Spirit is involved with the fourth tier.
