Summoning Technique

The Summoning Technique is a technique that, hence its name, allows a user to summon a being that they have previously signed a contract with. To perform this technique, the user must first sign a contract with an animal or being. This is done in a variety of ways, but the most common of which is to sign a scroll with one's name using their blood for ink. Once this is completed, the user can then successfully summon the being in one way or another. As well as this, if the being is from another realm, then it will allow the user to summon different varieties and quality of summons.
==Acquiring a Summon==
Aside from the prerequisites for using Summoning Technique, including the necessary skill in Space–Time Ninjutsu, not much is in the way of a person looking to earn a summon. The most common way to do this is through another person who knows the Summoning Technique. More rarely, which is still possible, a person may find an animal or being out there to directly sign a contract with. Once they have accomplished this, the user can finally use Summoning Technique, although there are some rules and stipulations tof follow.
==Limitations of the Summoning Technique==
To begin, one must know how they can summon animals in combat. This begins with knowing the guidelines when creating NPCs for summoning, if you aren't already given a set character or so on. Further in the same regard, one must know three important rules when determining their summon's powers. These rules are: Time, quality, and quantity.
There are different levels to the Summoning Technique, beyond its most rudimentary use. This largely depends on the amount of chakra used for the summoning, which leads to so many different doors to explore. The three most common of which are A, B, and C-rank summons. The guidelines on creating and using summons based on each summoning type can be found below.
===C-Rank===
C-Rank summons are the most common kind of summoning, and can fit into nearly any type of situation. They are like the footsoldiers of their corresponding realm, if they have one. Attributes refer to how many points a C-rank summoning can have. Bukijutsu refer to the fighting style a summon can possess. Duration refers to how long they are naturally summoned for. Combat refer to the amount of combat stars a summon starts with.
*Attributes: 25 Points.
*Bukijutsu: 1 Bukijutsu.
*Duration: 2 Rounds.
*Combat: 1 Combat Star.
===B-Rank===
B-Rank are more individualistic summons, and typically stand out if not because of their sheer strengths. It is at this level that you begin to see summons with special abilities that set them apart from the common rabble.
*Attributes: 50 Points.
*Bukijutsu: 2 Bukijutsu.
*Duration: 2 Rounds.
*Combat: 2 Combat Stars.
===A-Rank===
A-Ranks are among the most powerful of summons, typically being the elite few of their respective realms. Their power is immense, as they also tend to be in size.
*Attributes: 75 Points.
*Bukijutsu: 3 Bukijutsu.
*Duration: 3 Rounds.
*Combat: 3 Combat Stars.
===Time===
The exact amount of time a summoning is leased usually has a standard, typically being two to three rounds. However, when first summoning said creature you have the option to summon them for a longer time. Every additional point of chakra spent towards the duration of the summoning is equivalent to one additional round of time that the summoning will possess. In example: Ninja A has a C-Rank summoning, but wants to keep them around for three rounds instead of two. So instead of spending two points of chakra, as per usual, they would spend three instead.
===Quality===
As mentioned before, the quality of a summon can also affect the amount of chakra used. Each type of summoning requires a different amount of chakra, the exact amount usually depends on the summoning's level. Each corresponding level matches up with the amount it takes to use a jutsu of the same caliber. Two points for C-Rank, three for B-Rank, and five for A-Rank. Although some summonings may require an additional amount if they have abilities beyond the standard ones.
===Quantity===
In a case where one is not summoning a unique NPC, they can summon another of the same kind of animal as long as they are contracted to a realm and not an individual. The cost of this is two times the regular amount of chakra spent. In example, Ninja A wishes to summon two toad warriors from Mount Myōboku, so in order to do so he must spend four chakra points instead of the usual two.
