Ayda's Ice Beast

You touch a willing living creature, and for one minute, the temperature within one foot of that creature lowers until it is encased in ice. The creature's movement speed is halved and its creature type is replaced with the Elemental type. The creature gains +2 to its AC, vulnerability to fire damage, resistance to all non-magical damage, and immunity to cold and poison damage for the duration. All melee attacks done while under this spell have an extra 1d8 cold damage added onto the damage roll.
