Unicorns are celestial creatures, taking the form of a large horse with a horn attached to the forehead. These creatures are known to also be friendly towards the Fey, and can often be found within forests, where they often make their homes. Unicorns are also known to have healing powers, being able to cleanse creatures of wounds, disease and fatigue. They have also been known to possess powers of teleportation.

You have made a pact with a mystic stallion, a type of unicorn which is said to have been given more power by the gods, which it will share with you, either in return for services already rendered, or favours yet to be called upon. Like the Fey, these types of creatures are known to be conniving and mischievous, and may have tricked you into this pact for it's own mysterious gains.

 

Natural Affinity

When you make this pact at first level, the mystic stallion you ally yourself with shares with you the secrets of the natural world. You gain a resistance to poison damage, and are able to talk to animals, and understand their responses.

Rainbow Blast

The next gift given to you by the stallion is the gift of light. At level 6, roll a d10 whenever you use your action to cast the eldritch blast cantrip. On a 9 or a 10, you may change the damage type to any damage type of your choice until the start of your next turn. When this happens, the next eldritch blast which hits an opponent heals a friendly creature of your choice for half the hit points removed from the creature.

Also, if you score a critical hit with either a weapon attack or a spell attack, you can force a constitution saving throw on the target of the attack. If they fail, they are considered blinded until the end of their next turn. The DC for this ability is the same as your spell save DC.

Forest Secrets

As your bond with the stallion increases, he blesses your mortal body with unending vigour, as well as sharing with you the secrets given to them by the Fey in hushed whispers.

You gain an immunity to disease. You also gain the ability to cast the misty step spell once per short rest.

Herd Master

At the height of your friendship with the stallion, they grant you the use of their divine herd, which will come to you when your need is most dire.

When you gain this feature at level 14, you may use your action to summon 1d4 unicorns (which use the stat block in the basic rules). Each unicorn immediately uses one of it's actions (and movement if required to reach a target) before disappearing back to their stallion's domain.The unicorns have access to any of the actions on their stat blocks, including the legendary actions.

This feature can only be used once per long rest.
