Ice-Ice Fruit

Passive. Your body is made of ice, granting you the following benefits.

• Immunity to cold; bludgeoning, piercing and slashing damage from nonmagical attacks.
• Ice Aura: Each creature that starts its turn within 3m of you must make a Constitution saving throw. On a fail, a creature suffers (2d8+Con) cold damage and its speed is halved until the end of its next turn. If a creature fails this saving throw for two consecutive times, it is restrained, and if it fails three consecutive times, it is frozen and petrified by the ice. If a creature receives 10 or more fire damage on a single turn, it counts as a success for its next save.
• Proficiency in Athletics and Constitution saving throws, or expertise if you are already proficient.
• You are considered an Elemental.
