Ultima IV: Quest of the Avatar/Magic

Classes and MP
In the subsequent episodes of Ultima, the Avatar will always be the character with the highest MP.

Spell list
In the table below, the following abbreviations are used for the reagents:
 * Ash: sulphurous ash
 * Gin: ginseng
 * Gar: garlic
 * Sil: spider silk
 * Mos: blood moss
 * Prl: black pearl
 * Nig: nightshade fungus
 * Man: mandrake root

For a list of the locations of the reagents, check the Britannian Yellow Pages and the side quests page.

In the table below, spells are grouped by type, then sorted by the gold cost of reagents. Indeed, what determines the availability of a spell are not magic points, but the gold to buy reagents.

Classes and MP
Remember that in the NES version "Int" and "Dex" labels are swapped.

The Shepherd has no Magic Points, but she is the only character who can use the Sheep Flute, an item that casts the Sleep spell on all opponents.

In the NES version, when the Stranger becomes an Avatar, his/her maximum MP promptly becomes 99. This holds true for every profession. In the subsequent episodes of Ultima, the Avatar will always be the character with the highest MP.

Prompt specifies whether a spell is available since the beginning of the game ("yes") or if it has to be learned ("no"). After one or more characters told you about a new spell, it can be learned by going to "Spells Unlimited" in Moonglow, and telling the shop owner the proper ingredients.

In the NES port, four spells were removed: Undead (equality amongst enemies), Open (no trapped chests), Up and Down (game breakers). On the other hand, three new spells were introduced, bringing the total to 25: Reflect, Squish and Defeat.
