Mana is the amount of mental energy you have to expend. It is registered as
points in the game and they regenerate just as normal hitpoints do, or
occasionally, through magical means. It is listed as MA:(Mana points) in
the prompt.
The amount of mana available is based on the person's mind attribute, and
will increase per level depending on that stat. It is consumed by actions
that take a great deal of mental discipline, such as those performed by
druids, magicians/sorcerers, or doctors.
Mana increases by 5 points for every 1 point of mind.
Mana increases based on bonuses from worn equipment.
Mana increases based on bonuses from spells and skills.
