Path of the Primordial

When you select this class at 3rd level you gain proficiency in the Primordial language and all of its dialects (Aquan, Auran, Ignan, and Terran).

Starting at 3rd level, you begin to connect with the elemental planes of existence. At the beginning of each day roll 1d4. Depending on the roll, you
gain resistance to that element while raging, for the duration of your rages throughout the day.

Beginning at 6th level, while raging you can unleash an aura of elemental fury that alters the terrain around you. The effects of your aura depend on your element resistance gained from your Tides of Elemental Chaos feature. The aura emits from yourself at a radius of 10 ft. Your Aura of Chaos save DC equals 8 + your proficiency bonus + your Constitution modifier.

Kossuth’s Eternal Pyre. Cinders from the Plane of Fire surround you with a burning inferno. Whenever a creature enters your aura for the first time or starts its turn there, it must make a Dexterity saving throw. On a failed save, the creature takes 2d6 Fire damage. On a successful save, the creature takes half as much damage.

Frigid Depths of Istishia. Drawing upon the depths of the Plane of Water, you surround yourself with a mighty torrent of freezing water. Whenever a creature enters your aura for the first time or starts its turn there, it must make a Dexterity saving throw. On a failed save, the creature takes 2d6 Cold damage. On a successful save, the creature takes half as much damage.

Crag of Grumbar. The mighty Plane of Earth alters the terrain around you with cracking and shifting rocky earth. Everything within your aura is considered difficult terrain and all creatures other than yourself move at half speed while within your aura. Additionally, whenever a creature enters your aura for the first time or starts its turn there, it must make a Dexterity saving throw. Upon failure, the creature is grappled as its feet sink into the shifting earth. A grappled creature can use its action to escape. To do so, it must succeed on a Strength (Athletics) or Dexterity (Acrobatics) check against your Aura DC.

Akadi’s Relentless Cyclone. A mighty tempest from the Plane of Air surrounds your space. This tempest disperses fog, smoke, and other gases. In additional, whenever a creature enters your aura for the first time or starts its turn there, it must make a Dexterity saving throw. On a failure, they are knocked prone or pushed 5 feet away from you by the mighty winds.

Starting at 6th level, while raging you gain the Siege Monster feature causing all your melee attacks to deal double damage to objects and structures.

Beginning at 10th level, while raging you can channel elemental energy into your melee attacks to devastating effect. Be expending uses of your Hit Dice you can roll them and add the total as additional damage on your melee attacks. You can only use an amount of Hit Dice equal to your Constitution Modifier (minimum of 1) per attack. The damage type is tied to your Tides of Elemental Chaos feature and your Aura of Chaos feature.

At 14th level, you no longer have to roll 1d4 to determine your elemental abilities. After finishing a long rest, you can decide which Plane of Elemental Chaos you are attuned to for the day. In addition, while you are raging you have immunity to the corresponding damage type from your Tides of Elemental Chaos feature instead of resistance.
