Ultima IV: Quest of the Avatar/Magic

Classes and MP
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.

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

Reagents
Six reagents can be purchased in every apothecary shop, but the remaining two are the subject of side quests.

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

In the tables 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 (found in side quest)
 * Man: mandrake root (NES manroot; found in side quest)

Spell list
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. The GP cost of reagents does not consider Fungus and Manroot, that can be obtained for free.

Prompt specifies whether a spell is available since the beginning of the game ("yes") or if the characters should find something during the game (the recipe and/or some rare reagents). Three spell prompts are labeled as "new mix": the manual describes a recipe, but the characters can find a better recipe to cast them in the game. In the SMS port, instead, two of those recipes (plus a third one) are completely omitted from the manual, and the player can learn it from the game only.

Spell Types:
 * Healing: spells that can be used both during and after battle (exception: Resurrect);
 * Field: spells that can only be used outside battle;
 * Support: battle spells that target the allies;
 * Disable: battle spells that target the enemies but deal no damage;
 * Attack: battle spells that damage the enemies.

NES spell list
In the NES port, the recipes and the price of reagents are different. Furthermore, four spells were removed: Undead (no enemy sets), 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.

Prompt specifies whether a spell is available since the beginning of the game ("yes") or if the characters should find something during the game (the recipe and/or some rare reagents). 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 original versions each of the 26 spells names start with a different letter. In the NES version some spell names were modified: for this reason, some spell names in the table below are preceded by the initial letter of the original and a slash (e.g. the original "Resurrect" spell is listed in the table below as "R/Life").
