Create hivemind

You become the center of a multi-creature web of thoughts which you can expand and command. When you first cast the spell the hivemind consists of yourself and the creatures used in the casting of the spell. You can add a creature to your hivemind by performing a 30 minute ritual, this ritual must be uninterrupted and the target creature must remain within 30 ft of you. A creature can only be added to the hivemind if it has a CR or half your level or lower.

When a creature is added to the hivemind you gain access to the creature's memories and you can command one member of the hivemind as a bonus action. Each member of the hivemind roll initiative separately and has the statistics they had before they joined the hivemind except for their wisdom, charisma and intelligence which automatically becomes 7 and will take actions to best assist you during their turns if you have not commanded them.

Whenever a member of the hivemind is killed you take 3d8 psychic damage, this damage cannot be mitigated or reduced in any way. If a member of the hivemind takes psychic damage every other member of the hivemind also takes the same amount of damage. If you are reduced to zero hit points all other members of the hivemind become incapacitated and if you die all the other hivemind members also die.
