Weave Fragment

You spend 10 minutes melting down small pieces of metal and sacrificing your life force for as long as the creature lives. You can summon a weaveborn familiar when doing so choose one of the following choices. As long as this weaveborn lives your maximum hit points are reduced by 2d6. After this spell is cast you cannot cast it again for the next 24 hours.

Scout

Defender

Magus

Each of these summons a weaveborn to fit the need of that word. As an action you can send the creature back to the weave while keeping its form and making it appear in a space you can see within 10 ft. of you. This creature share initiative with the caster and can be commanded to act as a bonus action if not commanded the creature stays still.
Also as action, you can see through the eyes of the weaveborn when you do so you lose all of your senses as long as you are using the senses of the summon. As an action, a willing weaveborn fragment within 5 ft. of a caster can be sacrificed to cast another weave spell. Allowing the caster to take no damage from the casting. 
(When this happens the maximum hit points return to the summoner but are not healed.)
