Pool (Aura)

In Sphaeronics, a Pool, is the amount of aura a user contains at any given moment. There are two different kinds of pools: Channelable and Maximum.

Channelable
A person's channelable pool is all the aura they have available to use at a given point. This pool decreases in size with each spell cast. A channelable pool may be refilled with potions, foods, or rest until it reaches a person's maximum pool.

Maximum
A person's maximum pool is all the aura they may possess at one time. A user's maximum pool increases with age and practice but can also be damaged with repeated improper use of aura or certain curses, poisons, etc. The channelable pool may never pass the maximum pool unless a person has been enchanted.
