Spells require a certain amount of Mana, which can be increased by raising the Intelligence statistic, or by equipping items with Mana Increase and/or Intelligence Bonus properties.
There are 7 schools of spell casters that can conjure a total of 137 spells: Casting certain spells are based on (or can lower) the practitioner's karma. Under certain conditions, some spells can be interrupted during casting, while others cannot. All spells require the use of Words of Power. In contrast, Imbuing offers no direct adventuring benefits. However, Focus also offers the adventuring benefits of up to 12 points of stamina recovery and 6 points of mana regen. Mindblast is also cold damage and casts faster than Energy Bolt/Bombard as it is a lower circle, Bombard is a physical damage version of Energy Bolt so not particularly useful against a monster with high physical resist. Currently, both Imbuing and Focus can act as the secondary skill to Mysticism, strengthening its spell duration, damage, or mitigation effects. While some spells require the use of components, or reagents, in order to cast them, others do not. Mysticism has the high damage 7th circle spell Hailstorm - cold damage - which Oni are weakest against. By tapping into the mythic powers of the multiverse, skilled characters are able to: attack enemies aid themselves and allies move objects and themselves create things out of nothing summon creatures and a whole host of other actions that most people imagine when they think of magic. In UO, the term Spells is used conventionally.
