Description: The user will perform three handseals for the creation of a familiar of higher sentience formed of Algae; the Sentinel. A Sentinel typically appears as a humanoid entity, devoid of real facial features, lacking a real neck, stocky in proportions, possessing arms of exaggerated size that drape down to below its knees, stump like legs and three cylindric fingers that sprout from each hand, which are indistinguishable from its arms as it lacks any real joints or contouring, capable of ranging from human size to truly gargantuan proportions such as that of 'Great Stone Golem'. True to the formless nature of Algae however, the Sentinel is freely capable of shapeshifting from one form to another, adopting any shape or size that pleases him or his summoner. As an extension of this it also possesses the ability to regenerate, anything less than full destruction will allow the Sentinel to swiftly re-assume its full power and whatever shape it was in, or a new shape should it so wish. The Sentinel will continue to persist so long as the Algae that comprise it exist. Depending on the attributes instilled on creation, either a Red or a Green Sentinel will be created, Red Sentinel's are typically comprised of Algae that thrive when embedded in sediment, near rocks or in shallower waters, as opposed to Green which prefers deep, free waters; as a result, Red Sentinel's are capable of utilising all Algae techniques, and S rank and below Earth techniques, whereas its counterpart, the Green Sentinel, is proficient in all Algae techniques, and S rank and below techniques of the Water element. While Sentinel's employ a running speed that is, at best, extremely lethargic (half that of the users), it is capable of phasing through sources of earth and algae (Red Sentinel) or Water and Algae (Green Sentinel) at up to twice the users base speed. While only one Sentinel can be created at a time, a Sentinel is capable of dividing itself into multiple iterations of itself, however it is only capable of creating up to one fully functional copy at a time, the rest will lack the ability to utilise jutsu, therefore while its physical and innate power will be split among them, its abilities won't exactly be.
- Can only be used twice, when created lasts four turns, with a three turn cool down between usages.
- Any jutsu that the Sentinel utilises counts towards its move count, innate abilities are passive, however creating a fully functional copy requires a move.
- Once a Sentinel expires or is destroyed, the user will not be able to utilise Algae techniques above A rank for three turns.
- Spores are constantly released in the Sentinel's wake.
- Regardless of the users will, so long as the user is alive, a Sentinel will passively sap 10 chakra per turn to remain functional. The user can however forcefully will the Sentinel's destruction, or, can will a Sentinel into a state of non-chakra-sustained dormancy, turning the Sentinel inactive until they re-activate it again (30 chakra cost for reactivation).
