The Maelstrom

Forming a pact with the eccentric beings which exert control over storms and tempests, you have gained the ability to cause natural phenomena that stirs the skies around you. Entities that have the power to summon storms include the old thunder and sea gods, like Zeus, Ba'al, Indra, Thor, and Susanoo.

Expanded Spell List

The Maelstrom 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.

Maelstrom Expanded Spells

1st	thunderwave, longstrider
2nd	levitate, dust devil
3rd	call lightning, slow
4th	storm sphere, arcane eye
5th	control winds, maelstrom

Incandescent Streak

Starting at 1st level, you learn to harness the boundless energies of the storm in which your patron reigns supreme. When you perform a ranged weapon or spell attack, you may imbue the attack with incandescent energy. If you do, you gain additional ranged weapon attack modifier or spell attack modifier equal to twice your Charisma modifier (Minimum increase of 1). Your attack will also emit a bright light that illuminates a radius of 5 ft. for 5 seconds upon a hit on an object or creature.

You can do this up to a number of times equal to your Warlock class level, and all uses are regained upon a long rest.

Rolling Tempest

Starting at 6th level, the wrath of your stormy and eccentric patron slumbers within you. During your turn, when you make a hit with your Eldritch Blast, an attack imbued with Incandescent Streak, or any attack that originally has the Thunder or Lightning element in its damage, you can use your bonus action to deal additional 2d8 thunder or lightning (of your choice) damage to the hit creature. At 10th level, this increases to 3d8. If the attack had made a critical hit, your Roaring Tempest deals twice the damage and the creature is stunned until the start of your next turn.

You may use this feature a number of times up to your Charisma modifier, with a minimum of 1, and all expended uses are regained when you take a short or long rest.

Glory Sovereign

Starting at 10th level, you gain resistance to thunder and lightning damage. Additionally, you gain the ability to walk on water, by creating a swirling vortex in the water body that supports your weight. If you are submerged in a non-magical body of water or liquid substance, you may use your action to command the body to bring you to the nearest surface, where you may regain your footing.

Catastrophic Avatar

Starting at 14th level, as an action, you may summon the avatar of your patron. For an hour, a physical image of your patron is created, at your description, sentient and possessing all the powers befitting such a being, but limited due to the constraints of this realm. The patron is friendly but equally indifferent to you due to its elevated position, and is also friendly to all creatures that are innately thunder or lightning in nature, which will regard the patron to be friendly as well. It is indifferent to all other creatures. The avatar listens to your commands, but is not subservient and will only choose to follow them when it wants to. You are able to communicate with the avatar through thought, and it can understand you perfectly regardless of your language, but other creatures must know the Auran language in order to communicate with it. The avatar disappears at the end of the time limit, when it is killed, or when it decides to leave of its own accord.

Your avatar will have the stats and abilities of a air elemental, and takes its turn immediately after yours. Additionally, it has the Rolling Tempest class feature and the prismatic spray spell, of which it can cast up to two times for every manifestation and may only deal lightning damage (i.e. do not roll 1d8 to determine the element or the number of rays). The avatar will remember all it has experienced while it is summoned by you, but will not gain any experience in battle or otherwise.

Once you have used this class feature, you may not use it again until after a long rest.
