The Ancient Frost

Your patron is a powerful wielder of ice and cold. You have bound yourself to an ancient god of cold, or maybe a cunning ancient dragon of some sort that uses the powers of winter to its example. Your pact allows you to use these powers as your own, to bring eternal winter to your enemies, or to use the durable ice as a ward to protect those you care for. This being may ask you to bring them the souls of slain enemies or present them with the frozen sculptures you create. Beings of this nature can be the likes of Auriel, an ancient white silver dragon, or an elemental being of frost hailing from the endless winters of the elemental plane of water.

Decree of Frost

At first level, your cold magic is much more potent, when you cast a spell that deals cold damage you can add your charisma modifier to one damage roll of the spell. Additionally, you gain resistance to cold damage and become immune to the effect of extreme cold.

Circle of Icicles

At 6th level, you deepen your connection to your patron, and the abilitiyu to summon shards of frozen ice. As a bonus action, you can conjure a circle of icicles that point away from you and rotate menacingly around you. The number of icicles is equal to your proficiency bonus. the icicles remain for 1 minute, until they are all expended, or until you use a bonus action to dismiss them.

When you deal damage with an attack or cast a spell, you can expend and launch one icicle at one creature that was dealt damage by the attack or spell. For each icicle, make either a melee or ranged spell attack against the target. You can only launch up to two icicles per turn. On a hit, the creature takes 1d8 cold damage.

You summon these icicles as many times as your proficiency bonus and regain all uses on a long rest.

Hoarfrost

At 10th level, you can summon the chill of never ending winter and unleash it's embrace on a creature within a 30ft range. As an action, a creature of your choosing must make a constitution saving throw against your spell save DC, on a fail the target takes 3d8 cold damage and becomes Restrained, the target must make another constitution saving throw at the end of it's next turn, on another fail the target becomes incapacitated, at the end of the targets turn thereafter it must make a final constitution saving throw, on a fail the target is Petrified. On a success the target takes the damage and suffers none of the other effects.

Unearthly Cold

At 14th level, you can manifest your patron's wintry domain, becoming an unearthly winter. As an action you can transform into a being made of pure cold energy and gain temporary hit points. these temporary hit points are equal to your warlock level + your charisma modifier. Your held and equipped items transform with you and you retain their benefits.

In addition, you gain the following benefits while transformed this way:

• You gain resistance to bludgeoning, Piercing, and slashing damage
• you have a flying speed equal to your walking speed and can hover. You can move through openings as narrow as one inch wide, including enemy spaces.
• While you are using your Circle of Icicles you never run out of icicles and the cold damage is increased to 2d6.
• Whenever you cast a spell, the spells damage type is replaced with cold. You ignore resistance to cold damage and you bypass cold immunity, turning it to resistance. These effects do not stack with each other.
• In this form you gain immunity to cold, however you gain vulnerability to fire damage.

This form lasts for 1 minute, once you use this feature you cannot do so again until you finish a long rest.
