Awaken

Awaken—first entering the mage's repertoire in Ultima IV—is a spell that bestows the effect of rousing its unconscious target from their slumber, whether a consequence of natural fatigue or induced by magical means such as the Sleep enchantment, as well as its field-based and alchemical counterparts. The negation affects only a single beneficiary; its greater variant, Mass Awaken, is capable of bestirring an entire group.

Orange potions fulfill the same purpose as Awaken.

Trivia

 * In Ultima VI, Dispel Magic counts an able substitute for Awaken among its more versatile effects.
 * In Lynn Abbey's Ultima Saga, Balthan stayed awake for twenty days before locking himself behind his magic barrier using An Zu, and has stashed away enough garlic and ginseng to keep himself awake for months.
