This unmelting piece of ice fits comfortably in a human hand, but it radiates intense cold. An eternal blizzard over an icy landscape can be seen by looking deep within the crystal.
Elemental Ice is a physical piece of the plane of ice. It functions as the material component for the plane shift spell when traveling to the ice plane.
Chunks of Elemental Ice sometimes fall from ice paraelementals or mephits upon death. Those with the correct knowledge and materials can use Elemental Ice to summon (or recreate) an elemental of various size and strength. Sometimes elementals can spontaneously reform from Elemental Ice, especially if enclosed in a small space like a backpack, or if the environment is cold.
Direct contact with Elemental Ice causes 1 point of damage per turn to unprotected flesh, but resistance to cold negates this damage. If it's pressed against a metal weapon, it allows the weapon to deal an additional 1d6 cold damage on a successful hit, but causes a -2 to hit if the wielder needs to hold the ice against the weapon. Some tinkers have rigged cages to hold the ice against the weapon, which negates the penalty to hit.
Elemental Ice can freeze liquids on contact, and may ruin magic potions by freezing. It can also negate magical fire as a dispel magic spell cast at 5th level. If the dispel magic works against at least mid-power fire magic (a 3rd level effect or greater), the ice sublimates and disappears with the sound of cracking lake ice.
