Yuki Yuki no Mi (Snow)
Devil Fruit, Very Rare
Type. Solid Logia
Fruit appearance. A white and light blue starfruit with snowflake patterns.
Description. Allows its user to create, control, and transform into snow at will.
Sea Weakness. You are weak to water and seastone.
Logia Immunity. You are immune to bludgeoning, piercing, and slashing from nonmagical attacks, as physical objects pass through your snow body. Additionally, you are immune to cold damage and you can move across Difficult Terrain created by ice or snow without spending extra Movement.
Elemental Form. You can use the “Logia Elemental Form” feature listed under “Designing a Logia Devil Fruit Sheet”.
Crippling Frost. You learn the Frostbite Cantrip. Any time a creature takes cold damage from your Devil Fruit Spells or Cantrip, its speed is reduced by 10 until the start of your next turn.
Snow Demon. As an action, you can spend 3 devil fruit charges to enter a snow demon form for 1 minute. When you do so, your size grows to large, you gain 30 temporary hit points, and you grow an icy fanged maw, which is a natural weapon you can use to make unarmed strikes for the duration. If you hit with it, you deal piercing damage equal to 2d6, plus an additional 1d6 cold damage, instead of the bludgeoning damage normal for an unarmed strike. Additionally, when you hit a creature with your bite attack in this form, it must succeed on a Constitution saving throw against your Devil Fruit save DC or become stunned until the start of your next turn.
Spells (Snow Techniques). This devil fruit power has 13 charges. You can use an action, bonus action, or reaction and expend 1 or more of its charges to cast one of the following spells from it without needing to expend material components: armor of agathys (1 charge, can cast at higher levels by spending additional charges), snilloc’s snowball swarm (2 charges, can cast at higher levels by spending additional charges), elemental weapon (cold; 3 charges, can cast at higher levels by spending additional charges), ice storm (4 charges), cone of cold (5 charges), investiture of ice (6 charges), wall of ice (6 charges). The devil fruit regains expended charges daily at dawn.
Awakening (Ten-Layer Igloo). Once you’ve awakened your power, you can use an action to cast Prismatic Wall, with each layer being Blue, without expending any charges or material components. You can’t use this action again for another 24 hours.
