Spells Unlimited

Spells Unlimited is a special facility in Moonglow which appears only in the Nintendo port of Ultima IV.

Description
Spells Unlimited was an establishment which offered to transcribe spells into the Stranger's spellbook once they learned the correct configuration of herbs necessary to cast them. This service was free, but depended on the player's knowledge of a spell's recipe and would only allow one to record spells which had previously been mentioned by non-player characters.

Once a spell was appended to the hero's book, the character could then cast it until they ran out of herbs, as the pre-mixing of spells was not required in this version of the game.
