Spell points, often referred to as mana, increase at approximately the same rate as hit points. (See "help hitpoints"). They regenerate with time, usually faster if you are intoxicated. Many things can use/reduce your spell points, usually casting spells or using the "shout" command. Several guilds use spell points extensively, and some guilds do not use them at all. You will quickly learn about your spell points as you play the game. See also: guilds, hitpoints, pub, score, shout.
