Cold mages know that cold energy can be found, and therefore shaped, into many
forms. With a little coaxing, a large amount of water can be chilled and
condensed past its 'ice' state to a more pure state of cold energy. Using this
spell, a cold mage can form a weapon-like energy form. While itself
insubstantial, it can freeze victims on a hit, and chunks of ice continue to
orbit the weapon, drawn in like gravity.
Cast transformation makes a better weapon.
