The Frozen Monarch

The frozen monarch is a powerful ice elemental who resides in a castle in the para elemental plane of ice and wishes to expand his frozen kingdom by any means necessary.

Mantel of Frost

Starting at 1st level as a subject of the frozen monarch you become adept at residing in cold climates. You ignore difficult terrain caused by ice and snow and gain cold resistance.

Conquering Cold

Starting at 1st level you can grow the turf of your patron. As a bonus action you can cause the ground within a 10ft radius of you to freeze over, making it difficult terrain. At 5h level this is increased to a 15ft radius. At 11th level it's increased to a 20ft radius and at 17th level it is increased to a 25ft radius. You can use this feature twice per short rest.

Frost Guard Embodyment

Starting at 6th level you are imbued with power of the monarch's frostguard. You become proficient with heavy armor, but any heavy armor you wear becomes covered in creeping frost. While standing on ice or snow you deal an extra 2d6 cold damage with melee attacks and you have +2 AC.

Hand of the Frigid Lord

Starting at 10th level your rising in the ranks of the frozen monarch has granted you the power to shape his kingdom to some degree.

As an action, you can either:
Target up to 3 spaces that are covered in ice or snow. A 10ft tall 5ft radius pillar of ice rises up. If a creature is standing on the pillar as it rises it can make a dex save against your spell save DC to move to a space adjacent to where the pillar was created. If the pillar rises against a ceiling and a creature fails the dex save it will be restrained between the pillar and the ceiling. As an action the restrained creature can make a strength check against your spell save DC, breaking free on a success.

Target a creature standing on ice or snow. Icicles will fire up from the frozen land attempting to skewer it. The creature makes a con save. It takes 8d6 piercing damage on a fail and half on a success.

You can use this feature up to twice per short rest.

One with the Frost

Starting at 14th level, you can become one with the frozen kingdom. As a bonus action while you are standing on ice or snow, you can sink into the frozen land and emerge in another space that has ice or snow within 120ft, provided that between you and the destination is an uninterrupted line of frost.
