Restoring mana

Mana regenerates automatically for all characters every pulse. The regeneration rate can be boosted by resting or sleeping, and also by wearing items with a mana regeneration bonus. Resting or sleeping on furniture with such a bonus helps even more.

The higher your intelligence and wisdom, the faster your energy recovers. Mana regenerates better under the slow affect, and more slowly under haste, hunger or thirst. Poison and plague slow the regeneration process, while decay halts it completely.

The better your class handles spells (magic or prayers), the faster your energy regenerates. For example, witches regenerate energy faster than paladins, and vampires faster than thieves.
