Artifice
From Ardrana
Artifice is one of the thaumaturgical schools of magic. It is composed of spells that store or channel magical energy through items carried by the wizard. In effect, the artificer is a wizard who creates temporary magical items for his own use. The advantages of this thaumaturgical method lie in the wizard’s ability to increase his spell power by carrying extra spells in various magical items and to unleash powerful enchantments with a single command word.
Note: Artifice originally appeared in this form in the Player's Option: Spells and Magic supplement for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
