Must be tricky to move when your feet are icicles. Would he "skate" around to move, or a sort of hover, like super-cooled semi-condctuors?
Also, someone else said that they're holding the spear upside-down. The proper grip would have the thumb-side of the hand aimed twards the business end of that sucker. Holding it at the ready, like in a fighting stance, the arm would be swung back, ready to strike, but yes- pointed downward (but more horizontal). At ease, standing like that, the spear would be pointing up.
