Hiyori (5e Equipment)
From D&D Wiki
Weapon (katana), legendary (requires attunement)
Hiyori is a razor sharp katana that has a frosty white tint to her silver blade. From her blade, an aura of cold radiates, frosting her blade further as well as where her blade meets her sheath. On her blade, near the guard, is engraved a flower and her guard depicts a snowflake with sapphires inlaid around the perimeter. Her wrap is a sleek white silk. This magic weapon has a +2 bonus to attack and damage rolls. Attacks with Hiyori also deal an additional 1d10 cold damage.
Heart of Ice
You can use your action to make a line, about 4 feet wide, of jagged and sharp ice spikes, about 4-6 feet tall, erupt across the floor (originating from the tip of Hiyori of 5ft in front of you) until it reaches the end of its 30 foot range. Creatures in the aoe take 3d6 cold damage on a failed DC 14 Dexterity saving throw, and half as much on a successful one. You must wait one hour before you can use this attack again.
