Upon casting this spell, the caster picks an element type (earth, fire, ice, lightning, water, or wind). This spell infuses the weapon touched with elemental energy.
The next time this weapon strikes a creature, it discharges the elemental energy. The spell deals an extra 1 point of damage of the elemental type chosen per level (to a max of +5) + your Charisma modifier against the target of the attack.
The weapon loses this property if its wielder drops it or otherwise loses contact with it.
