A burrowing ice elemental can pass through nonmagical ice and snow as easily as a fish swims through water. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other sign of its presence. A control water spell cast on an area containing a burrowing ice elemental flings the elemental back 30 feet, stunning the creature for 1 round unless it succeeds on a DC 15 Fortitude save.
This ability works like the spider climb spell, but the surfaces the elemental climbs must be icy. The elemental can move across icy surfaces without penalty and does not need to make Acrobatics checks to run or charge on ice.
When an ice elemental deals cold damage to a creature, that creature must succeed on a Fortitude save or be staggered for 1 round. The save DC is listed in the elemental’s stat block and is Constitution-based.
An ice elemental can see perfectly well in snowy conditions and does not take any penalties on Perception checks while in snow.
