The Frostbitten

Your patron is a being forged in ice and snow, a creature that has not only survived in the most inhospitable environments of the natural world, but has conquered its surroundings and bent the freezing elements to its whims. Whether you bend the knee to an ancient white dragon, battle in the ranks of a frost giant jarl, or hunt game to quell the appetite of an especially powerful abominable yeti, the connection you have to your patron grants you a hearty breath and an unflinching tenacity under even the most extreme conditions. 

Expanded Spell List

The Frostbitten lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Frostbitten Expanded Spells

Spell Level	Spells
1st	sleep, grease (coating the affected area in slick ice rather than grease)
2nd	darkvision, gust of wind
3rd	slow, sleet storm
4th	fire shield, ice storm
5th	cone of cold, hold monster

Rime-Touched

Starting at 1st level, you are most at home in the coldest regions of the world and your patron has gifted you with more potent magic originating from these freezing landscapes. You gain resistance to cold damage and whenever you deal cold damage to a creature with a warlock spell, the creature's speed is reduced by 10 feet until the start of your next turn.

Numbness

Starting at 6th level, your nerves have grown permanently numb from the cold, dulling pain and allowing you to weather attacks that might leave others reeling. You gain proficiency in Constitution saving throws and when you are subjected to an effect that allows you to make a Constitution saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

Additionally, whenever a creature is affected by your Rime-Touched feature, its speed is reduced by an additional 5 feet (for a total of 15 feet).

Legionnaire of Lifeless Lands

Starting at 10th level, your connection to the inhospitable, death-ridden tundras of the multiverse has hardened your spirit, granting you a sturdy soul that's not so easy to snuff out. You do not suffer from the effects of exhaustion (except for death), your hit point maximum cannot be reduced, and your proficiency bonus is doubled for Constitution saving throws you make.

Additionally, whenever a creature is affected by your Rime-Touched feature, its speed is reduced by an additional 5 feet (for a total of 20 feet).

Winds of Winter

Starting at 14th level, you can call upon your patron to send the bone-chilling winds of its domain to gnaw at the flesh of your enemies. As an action on your turn, choose creatures you can see up to a number equal to your Charisma modifier. Those creatures must succeed on a Constitution saving throw against your spell save DC or suffer the following effects:

- The creature gains vulnerability to cold damage

- The creature has disadvantage on attack rolls

- The creature's flying speed is reduced to 0 if it has one

- The creature loses concentration on any spells it is concentrating on

An affected creature can repeat the saving throw at the end of each of its turns, ending the effects on a success. Otherwise, the effects last for 1 minute. Once you use this feature, you can't do so again until you finish a long rest.
