Endless Winter (For Flavor)

Casts a blanket of snow and ice across the most northern and southern parts of a world near the North and South poles. No snow will be present at the equator parts of worlds and the snow and ice becomes thicker and more dangerous the closer you get to the poles. Blizzards randomly appear and any characters must make a CON savings throw or take 2d6 Cold damage. When the caster is killed, the spell ends.
