Cold Blooded

The magic of the elements can be seen all around the world.  Many creatures within the world can control some aspect of them and you are no different.  The power of ice is stronger than most may know and your control of the element is strong. The medium is not contained to just water, just as heat can turn rock into magma, so can cold effect everything around it.   Being able to bring forth the freezing power in the middle of a dessert or able to make winter last longer than normal in a mountain region, the effects of one that can control this element can be seen throughout the world.  

Ice in My Vains

You ignore exhaustion from cold weather.  Furthermore, normal sunny days are more irritating to you.  You add your charisma modifier to any spell that you deal cold damage with if your charisma modifier has not been added to the spell already. 

Ice Spear

At 6th level, you gain the ability to hurl an ice spear at a target within 60 ft.  As a bonus action, you make a range spell attack against a creature.  If the attack is successful the creature takes 1d4 cold damage.  This damage increases at level 12 to 2d4 and at level 18 to 3d4.  

Ice Block

Starting at 14th level, when you deal any cold damage to a creature.   You can spend 2 sorcery point per creature up to your charisma modifier to force those creature to make a constitution saving throw vs your spell save DC.  On a failure, the creature is stunned until the end of your next turn.

Blizzard Elemental

Beginning at 18th level, as an action, you can create an area of intense cold.  Snow begins to fall, blanketing everyone and everything in a half a mile radius.  If you use this feature underground or underwater, the snow falls on the surface and does not reach you.  You create a blizzard around you as the snow falls. Every creature within 30 ft. of you takes cold damage at the beginning of its turn equal to your charisma modifier. You are considered to have half cover while your blizzard is active. You can use your action to conjure an Ice Elemental.  The elemental appears within 30 ft. of you, acts during your initiative and will follow your orders.  You can do this a number of times equal to your charisma modifier.  All of these effects lasts for 1 minute.  All of the Ice elemental summoned with this ability immediately disappear.  The snow melts at normal speed. After using this ability, you must finish a long rest before using it again.
