Taming Bond

You spent up to one hour in a ritual to magically bond a creature (aberration, beast, monstrosity, plant, fey or dragon)  to you for life. the maximum Cr creature you can bound is equal your level + your Charisma modifier divide by half. if a creature has an intelligence of 6 or higher when the spell is cast it automatically fails. If the creature is conscious it may do a charisma saving test to resist it, If the creature is unconscious, charmed or cant resist it automatically succeeds. 

Once the creature is bound, it obeys and serves you faithfully. You can give it mental commands and you can fell it if you are in the same plane of existence. once the creature is bound, a link of metal filled with magic energy appears in your hand, if the link is broken, the creature can take a charisma saving throw to break free of the spell if it succeeds the creature is free of your command and can either become hostile, fled or remain friendly.  If it fails the test it remains bound to you and cannot be free anymore, and dies if you die.

If the metal link remains intact it can be gifted or sold, but not stollen. the new owner of the link nows commands the creature bound.    

this spell won't work on undeads, constructs or humanoids.

 there is no maximum number of creatures that can be bound by this spell.
