Eidomon are weird creatures with unique appearances. They can transform between a small “cute” form and a larger “combat” form. They live in a cosmic realm that acts as a metaphysical shield for the rest of Creation against objects that fall from the Real World into Elohim.


Ability Score Increase. Your Charisma score increases by 2, and your Dexterity score increases by 1.

Age. Ageless, most eidomon are thousands of years old. However, they behave as children when in their basic form and as adults in their megamight form.

Alignment. Eidomon wish to protect the Mortal Plane from the existential threats of the Real World. They are lawful good, even if they act chaotic.

Rarity. Unknown.

Size. In basic form, you stand around 2 to 3 feet tall and weigh around 40 pounds; your size is Small. In megamight form, you stand between 7 and 8 feet tall and weigh between 300 and 400 pounds; your size is Medium.

Speed. Your base walking speed is 30 feet.

Darkvision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness within the same range as if it were dim light. Absent even dim light, this vision is monochromatic.

Change Aspect. You can use your action to change size from Small to Medium or back again. Your gear changes size with you if it must to remain useful to you. When you change size, you gain the following traits.

Small (Basic). You can move through the space of any creature that is larger than you. Also, you can attempt to hide even when obscured only by a creature larger than you. When you use the Deception skill to make someone believe you are cute and harmless, you can add your proficiency bonus, provided you have little gear that seems threatening and your target doesn’t know you can change size. If you have proficiency in Deception, your proficiency bonus is doubled for this purpose.

Medium (Megamight). You gain 1 temporary hit point per level you have. In addition, you grow physical ports that can launch beams of force. To launch such a beam, you use your action to make a ranged attack, dealing 1d10 force damage on a hit. You can use your action to fire two beams at 5th level, three beams at 11th level, and four beams at 17th level, rolling a separate attack roll for each beam.

Languages. You speak, read, and write Common and Whimsy.

Unique Appearance. The appearance of each eidomon varies wildly from the rest. You are encouraged to draw your character’s basic and megamight forms so that other players can envision them as you do. Even though you can add cosmetic features when depicting your character, such as wings, claws, or extra arms, these features have no function in the game. Of course, you can work with your GM to have these features emulate traits from other races in this book.
