Thought domain

Chosen by a group of lesser gods you infiltrate the mind of your target and cause them to hallucinate anything you can think of. You communicate with your party members from miles away. You can even have your gods pool together their powers to try and meet your needs. You have total control over the mind both yours and your enemies. 

If this subclass is broken please let me know I'm hoping to run it in a game and want it to be as balanced as possible thank you. (Also if anyone has a better description that would be cool)

Bonus Proficiency

When you choose this domain at 1st level, you gain proficiency with heavy armor.

Infiltrate

At 1st level you can use your action to inifltrate a target creature you can sees mind. Roll Wisdom(Arcana) against target creatures passive wisdom score if
unwilling or automatically if willing. Once infiltrated target creatures surface thoughts are read and any attacks against target creature have a +2 to hit as long
as the attacker can communicate with you. These effects last one hour. On a successful save the target is aware of the attempt. You can use this ability a number of times equal to your proficiency bonus per long rest.
