Your patron is the embodiment of winter. This is typically a god associated with winter or cold, but powerful ice maidens, ice devils, and other creatures associated with the cold can serve as patrons.
Your patron seeks to immerse the world in eternal winter or bring about some similar fate. While you may not share this goal, you have sworn fealty to this being and you act as its agent to spread winter wherever you roam.

Deflective Ice
Starting at 1st level, you can bring a small chunk of ice to your aid. As a reaction when a creature makes a weapon attack against you, the ice shields you from the attack. The creature has disadvantage on its attack roll. Regardless of the result of the attack, the ice melts away immediately afterward. Once you use this feature, you can’t use it again until you finish a short or long rest.
Frozen Path
Beginning at 6th level, as part of your move for 1 turn, you can leave a layer of ice on the ground along your path. This ice persists for 1 minute. A creature other than you that enters a space of ice must make a successful Dexterity saving throw against your spell save DC or fall prone in that space. Once you use this feature, you can’t use it again until you finish a short or long rest.
Icy Body
Beginning at 10th level, your skin takes on an icy sheen. You are immune to cold damage, and you have advantage on Strength and Dexterity checks you make to escape from being grappled.
Wintry Blast
Starting at 14th level, you can designate a creature you see within 60 feet of you. It must make a Constitution saving throw against your warlock spell save DC. If it fails, it feels numbing cold emanating from your patron. The creature takes 10d10 cold damage and must make another Constitution saving throw. If the second saving throw fails, the creature is also restrained for 1 minute. A restrained creature repeats the saving throw at the end of its turn, ending the restraint on a success. You must complete a short or long rest before using this feature again.
Pact Boon
Pact of the Blade. Your pact weapon has a patina of ice and small icicles dangle from it. When you create or summon your pact weapon, you can choose whether it does its standard damage type or cold damage.
Pact of the Chain. When you conjure your familiar or change its form, you can choose the form of an ice mephit in addition to the usual options granted by the pact boon. When you use your action to command your mephit familiar to attack, it can use its breath or cast an innate spell instead.
Pact of the Tome. Your book is formed from rune‐etched sheets of ice that are cold to the touch to everyone but you. The book is immune to cold damage.
Eldritch Invocations
The following invocations are available to Frozen One warlocks.
Boreal Aura
Prerequisite: 3rd level, Frozen One patron
Ice and snow cascade around you. As long as you maintain concentration, your melee attacks do an additional 1d6 cold damage. Attackers within 5 feet of you who hit you in melee take 1d6 cold damage.
Horrific Wintry Visage
Prerequisite: 5th level, Frozen One patron
You can cast sculpt snow once using a warlock slot. Creatures that see your sculpture for the first time must make a successful Wisdom saving throw against your spell save DC or become frightened of the sculpture for 1 round. You must finish a long rest before using this invocation again.
