Imaginary Friend

The power of imagination is nearly unlimited. One may think of a wonderful place of peace and happiness, while another might think of death and violence as far as the eye can see. These patrons are as varied as the people who make them and each one is a unique entity. There are only a few people who have the mental skill to manifest these beings and even fewer who stay sane afterwards.

Glimpse into the Mind

At 1st level, you may look through the eyes of your Friend and see into the border ethereal for a time. While in this state you are blinded to your immediate surroundings but not deaf. Your Friend is under the effects of the spell See Invisibility while you are doing this and you can have them move as you see fit. This effect lasts for 10 minutes and then you are returned to your own vision. You may use this ability once every short rest.

At 10th level you may use this ability at will. 

A Friend in Need

At 6th level, your Friend is able to start affecting the physical world. When an ally of yours falls to 0 hp but not outright killed, you can spend your reaction to have your Friend help them back up to their feet. They are healed a number of hit points equal to your warlock level. This can only occur once per long rest.

At 14th level, your Friend rushes to your aid. If you fall to 0 hit points but not killed outright, this feature is used on you. This cannot happen more than once per encounter.

A Friend Indeed

At 10th level, your Friend is able to protect you from harmful influences affecting your mind. You become resistant to psychic damage, immune to Illusion spells and enchantment spell up to level 3.

At 14th level, this is increased to complete immunity.

Welcome to Wonderland

At 14th level, you choose a target and pull them into your imaginary world. This world is yours to create and explain. While they are trapped here their body is incapacitated and as long as you remain within 10 feet of them they will remain so. If something were to hit them in this state they would get a Wisdom saving throw against your warlock spell save. On a success they are able to leave if they wish. If a person where to remain here for a whole week straight they will be unable to leave unless a Greater Restoration spell is used on them.

You may only do this to one person at a time and use it once per long rest. If the person is trapped forever you no longer need to remain close and may target a new creature.

Power of Self

All of your power comes from within yourself. When you would gain a new warlock spell, you may choose from either the warlock spell list or the sorcerer's spell list.
