# Energy

Every Hero starts with a **base 100 Energy**. Energy is spent on adventures such as fishing, battling, and other actions.

### Energy Regeneration

Energy **regenerates over time** and can also be restored through other means.

* Hero energy regenerates linearly back to their max Energy over 48 hours. 

> $$
> \text{Energy Regen Rate} = \frac{\text{Base Energy}}{48}
> $$

* Heroes **regenerate energy even while on adventures**.
