Sheer Cold

Weapon Rare

The blade of this battleaxe is made from the shard of the Everglacier and never melts. Attacks with the axe deal cold damage instead of slashing, and you gain a +1 bonus to attack and damage rolls with this weapon.   When you roll a 20 on the attack roll with this weapon, the ground in the direction of the attack in a 15-foot cone is covered in slick ice for 1 minute, making it difficult terrain. When a creature enters the area for the first time in its turn or starts its turn there, it must succeed in a DC 10 Dexterity saving throw or fall prone.
