* Whenever Champions enter battles, the Energy will be decreased by 1.&#x20;
* Champions with higher grades have more Energy capacity.
* Energy can be recharged by using CUBE, or waiting for reset time for Energy recharge.
* For CODEX registration and ALTAR of DEATH, Energy doesn't have to be fully charged.
