Regeneration can be thought of as a form of healing. You gain regeneration
bonuses through spells and equipment.
If you have positive regeneration in either hit points, mana or movement,
they will be periodically increased by the amount of regeneration you have
(as seen in the attributes command).
There is a limit on the regeneration bonuses gotten through equipment.
Under the ATTRIBUTES command, you can get no more than 15 regeneration
points for either mana, movement or hp. You can have more regeneration points
than 15, however, you will only get the benefit of 13 points with equipment.
With spells, the limit is 18. And lastly, with INNATE REGENERATION, the
maximum would be 20.
The configuration 'showregen' will display a message every time you are
affected by a regenerative ability.
