Syntax: cast 'elemental infusion' <weapon> <spirit, water, air, fire, earth>
Calling upon their connection to the elements, Gaians can infuse a weapon
with an elemental power that will deal extra damage in combat. The effect
is temporary and will last longer the higher the spell is learned.
The duration of the elemental effect will only decrease when the weapon is
worn.
