Path of the Jötunn

In the furthest corner of the North, past the elven nation of Alpenfrost, there is nothing but a white and barren land. Only the hardiest of living things call that harsh region their home. Among them, is one of the last remaining Goliath tribes, known as the Ankalathai. In their tradition, when a youth is ripe for the coming of age rite, they are to receive what is called the Breath of Ymir. It is a strenuous and long process in which the youth receiving the Breath of Ymir must endure an entire night of that year's coldest winter day without any food, drink, nor clothing in a meditative state. If they are still alive by dawn, their breath will no longer be visible in the cold, proof that Ymir's breath has entered the youth. They are then marked by the tribe shamans with ancestral tattoos depicting their family line. This also serves as a source of power. The young warriors raised in the Ankalathai innately draw power from their homeland of the North by manifesting its fierce winters through their tattoos. 

Breath of Ymir

Blessed with a winter heart, you embrace the biting gales of the North. When you choose this subclass at 3rd level, you become resistant to cold damage, and traveling through any arctic region is not considered difficult terrain for you. Additionally, you can always sense when a blizzard is about to happen within a week's time.

Frozen Ink (Spellcasting)

The tattoos along your body are not only a depiction of your family line but the source of your tribe's power. You can choose between the frostbite or the ray of frost cantrips. You also learn spells related to winter at later levels as shown in the table.

Winter's Ire

The biting winds and hailing snow from within you are yours to control. Whenever you cast a spell or attack with a weapon that you are proficient in, you may add a number of d4's to the damage roll equal to your proficiency bonus as cold damage. Additionally, granted spells that you cast that have a save DC are increased by 1 DC.

Ymir's Kin

Your ancient blood connects to that of the famed father of Ice Giants, Ymir, granting you a great portion of his powers. Starting at 14th level, you are immune to cold damage and resistant to fire damage. As an action, you call forth the rage of winter as a spherical aura of 30ft. centered on you, protects creatures that you choose and harms those that are uninvited in the cold embrace.
