Frostwave

Frostwave
Evocation [Cold]
Level: Sor/Wiz 2
Component: V, F, M
Casting Time: 1 standard action
Range: 15 feet
Area: Cone-shaped burst
Duration: 1round/level or until removed; see text
Saving Throw: Reflex negates
Spell Resistance: Yes and no; see text

You create a wave of snow that covers every creature in a 15 foot cone; a Reflex save allows a target to completely avoid the wave. The snow sticks to the targets for one round per level (to a maximum of 6 rounds); a target can take a full-round action to remove the snow covering its body. In cold weather (below 40°F), the snow sticks twice as long to the target, while in hot environment (above 90°F), the duration is halved (round down).

Each round a target is covered with snow (starting the round you cast the spell), it takes 1d6 points of cold damage, and its speed is reduced by half. This is not countered by the haste spell; a hasted or slowed target still moves at half its modified speed, to a minimum of 5 feet. Spell resistance allows a target to resist the cold damage, but her speed is still halved due to obstruction by snow.

Material Component: A drop of water, which is frozen in snow by the spell.
