This spell is cast by a mage who wishes to cross a
body of water. The caster makes a sweeping motion with her arm over the water
she wishes to cross. This creates a disc of extremely low temperature just
below the water's surface, freezing that small area almost instantly. The
caster may then step on the disc and, controlling the apportation of the spell,
move across the water at a rate of 40 meters per round, simultaneously forming
a bridge of water behind him. This bridge can hold up to the effect total of
the spell in kilograms. The caster may, if she chooses, start the disc on the
opposite shore (up to one kilometer away and within sight) and have the bridge
form backward. This works nearly as well, except there is a chance of fog
fanning over the low temperature disc and obscuring it from sight. The caster
may dispel the disc and/or the bridge at any time. Otherwise, it will melt
naturally after the duration expires.
