Sheer Cold (Patreon)

Weapon (battleaxe), rare

The blade of this battleaxe is made from a 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 made with this magic weapon.

When you roll a 20 on an attack roll with this weapon, the ground in the direction of the target in either a 15-foot cone or line 30 feet long and 5 feet wide (your choice) is covered in a layer of slick ice for 1 minute, making it difficult terrain. When a creature enters this area for the first time on a turn or starts its turn there, it must succeed on a DC 10 Dexterity saving throw or fall prone. In addition, the target of the weapon attack must succeed on a DC 15 Dexterity saving throw or be restrained by ice until the start of your next turn. The restrained target can use its action to make a DC 15 Strength check. On a success, the target is freed.

The Everglacier resists the forces that act against it. Heat fails to melt it. Landscapes fail to slow its creeping progress. And much like the Everglacier, you too will fail to resist my chosen path.
