Masters touch is a spell often found in the repertoire of the adventurers that specialize in casting arcane spells. It grants casters the knowledge and experience to claim proficiency in whatever single weapon or shield they hold in their hands when the spell is cast. The lack of a somatic component means the spell may be cast in the midst of a fight while keeping ready whatever items stand between the caster and danger.

Proficiency is granted for only a single, specific item, although multiple castings allow for multiple proficiencies. For example, a sorcerer holding a short sword and rapier, with a buckler strapped to his off hand, could cast the spell three times, once for each weapon and shield.

Note that this spell does not grant proficiency for a class of item, but only for the one specific item held in the hand at the time the spell is cast. Should the caster set that item down or otherwise lose his or her grip on it, proficiency does not fade away; the proficiency is due to knowledge gained, not due to any transmutation of the caster or the item. The caster may therefore recover that specific item and continue to use it with proficiency until the spells effect runs out.

Masters touch does not convey any information about a magic item to the caster. The caster may not even be aware that an item is magical at all.

Arcane Focus: The item in whose use the caster wishes to be proficient.
