Manifest Eidolon

WARNING! The 'Eidolons' referred to by this feat DO NOT refer to the CR 12 Undead from Monsters of the Multiverse, these are, instead, highly variable companion Elementals whose base CR is 5! Please do NOT mix the two up.!GNINRAW

Over the course of your life, you have attuned yourself to a peculiar force, be it a God of dreams, or simply through meditation, or the divine touch of a higher power. Regardless, you have been granted a Companion, borne from your own thoughts and dreams. This powerful Tulpa-like creature is an Eidolon, and they will fight by your side to the bitter end.

You may take this Feat at any point you could normally or, with your DM's permission, at Character creation.

When this feat is taken, you have manifested, either through meditation or extreme emotion, a living embodiment of a part of your psyche. These entities can take all kinds of forms, from the reasoanble to the utterly bizarre. These entities originate from the Plane of Dreams and are intrinsically tied to your psyche.

An Eidolon whose HP goes below 0 will De-manifest, essentially a temporary banishment to the Plane of Dreams. They cannot truly 'die' unless you do. If they De-manifest, then you must meditate over the course of a Long Rest, fully awake and committed, to re-manifest your Eidolon. Doing so will result in either Negative Levels[a temporary loss of character levels] or a point of Exhaustion, depending on DM fiat.

As you level up, your Eidolon gains certain abilities and options to customization of your Eidolon that can alter how they function in and out of combat.

Keep track of your Eidolon and their growth via your Notes section. Eidolons gain an Ability Score Increase at the same levels you do, they cannot gain Feats.

1st Level Options:

Modified standard array: 18, 15, 14, 13, 12, 10

All eidolons use a modified Standard Point Arrray for their stats, and you can choose where each number goes to which stats based on how your Eidolon functions.

Pick a class: Brawler, Medic, or Wall

Brawlers: Heavy DPS-focused brute warriors. Brawlers are built for getting into the front lines and doling out impressive damage, either from melee attacks or spells. Brawlers gain the Multiattack option, where they may attack a number of times equal to your proficiency modifier. Brawlers have average AC and HP, their base attack is 1D8 times your proficiency modifier. Armor Class is 10+Proficiency Bonus. HP is 5 + 5X your level, Base D10.

Medic: Back-line Healers that shield and protect allies. Medics specialise in buffing and healing their allies and forego impressive damage in favor of keeping people alive. Unlike brawlers, Medics have the 'Healing Shiv' option, where any attack damage they do to an ally can be reduced by half and converted into healing instead. They have low AC and HP, their base attack is 1D6 times your proficiency modifier. Their Armor Class is 8 + your proficiency modifer, and their HP is 2+2X your level, Base D4.

Wall: Mid-line living barricades, Wall-type Eidolons are massive guardians that stop incoming damage outright. Walls have the weakest attack out fo all Eidolons, but make up for it be bing so absurdly durable that they could, potentially, outlive their summoners. They have incredibly high AC and HP, their base attack is 1D2 times your proficiency bonus. Their Armor Class is 14+ your proficiency bonus, and their HP is 6+6X your level, Base D12.

Base damage type: You can choose between Slashing, Piercing, or Bludgeoning.

Additional Movement type: You may select Climbing, Swimming, or Flying. Your eidolon has a base 30 movement speed in that field.

Scale: You select your Eidolon's size. Your eidolon can by any size you choose. It affects no other stats. If your eidolon is Large or higher, you may willingly demanifest your Eidolon, bringing it inside your mind to allow transporting your Eidolon through areas to small for its movement.

3rd Level Options: 

Elemental Affinity: An Eidolon's equivalent to a Sub-Class. you select a Primordial Element, and your Eidolon gains access to spells in their field. Your Eidolon may also do an additional 1D4 of one of their element's options. You CANNOT pick multiple elements, so choose wisely.

Earth: Acid, Poison and Bludgeoning

Air: Thunder and Lightning

Holy: Radiant and Psychic
