meditation
A magic-user with this ability will recover spent mana points more quickly while in a restful state. The concentration needed in order to meditate is only able to be attained while resting, not sleeping or standing. It is an automatic skill, although some people like to try and force it to happen (by typing 'meditate'). Studies have shown that there is no noticeable difference in meditative intensity, but some practitioners claim that proper posture while meditating enhances the experience. See showskill meditation for more details.
