This spell temporarily gives any one creature proficiency in the use of a specific weapon or tool seen and mentally chosen by the caster at the time of casting. The spell recipient may be the caster or another being touched by the caster during casting. The magic bestows temporary but complete familiarity with the use, care, and handling of the weapon and all accouterments. For instance, a wizard temporarily given proficiency in the use of a crossbow knows how to wind or cock it, which nearby implement is the necessary windlass (if it is that type of crossbow), and the different uses and proper loading of a variety of quarrels (if an array is present). Similarly, a scholar suddenly made familiar with a pickaxe would know how to use it to cleave rock along a plane, how to avoid striking sparks, how to strike so as to blunt the tool very quickly or as slowly as possible, what care to give it, and so on.
This magic does not confer any added Strength, reach, body weight, or other physical adjustments so as to allow the spell recipient to wield the weapon or tool most effectively; it just instills the precise and complete knowledge of how to do so. When the spell ends, this knowledge is forgotten, although memories of particular things done with the weapon or tool remain.
