Staffspell

This spell creates a stout staff of living electricity, 6 feet long. The staff inflicts damage as a normal quarterstaff, but for every five levels of the caster, the staff gains a +1 bonus to attack and damage rolls, to a maximum of +3 for a 15th-level wizard or higher. The staff inflicts double damage (2d6) on water-based creatures, save those immune to electricity.

The staff can be used as a light source, brightening from a dull glimmer to the equivalent of a light spell upon mental command by the caster. The staff can be used only by an individual with a weapon proficiency in staff; it cannot be passed to others for their use. If the caster releases the staff for any reason, including spell casting, then the staffspell ends instantly.

The material component is a small wooden rod 18 inches long, cut by the caster from a stout oak, and is consumed by the spell.
