Saint Beast Mode

Saint Beast Mode is a unique mode that is simular to  tailed beast mode and Sage Mode. In order for a user to use this mode they must have a summoning contract with on animal. The strength of the mode is determined by the strength of the bond the user has with their summon. It is the result of using the summoning chakra along with a ninja's normal chakra in perfect balance to drastically empower a ninja's abilities and usually changes the users form to match the animal.

Use
In learning the ways of this mode a mark is placed on the used and the summon. The two undergo a training that tests their bonds. If the bonds between the two are considered week the mark will shatter, destroying the contract they share and prevent the summoner from forming a contact with that animal again. However if the bonds are proved to be strong the mark will glow the change into that of the summoning animal on the summoner.

After which by balancing their chakra and their summonings the user is able to increase their strength and speed, as well as their form changing to match that of their summoning. Due to the nature of the mark the user does not need to summon their contract, but if they do the strength of the mod increases.
