Chakra

**Chakra** generally refers to the mystical energy within us that all shinobi use to perform their techniques. In this context, it refers to the attribute from the Power Score that measures the amount of Chakra that a shinobi possesses. This attribute is important to keep track of, as each rank of Jutsu costs a certain amount of points from your Chakra attribute to be performed. The attribute does not fully encompass the total amount of Chakra that a character can possess, however. In fact, there is a second layer to this number that is used whenever a shinobi has burned through their main reserves. This second layer is referred to as Auxiliary Chakra. Once this reserve is tapped into however, it comes with a severe debuff as character's begin to experience Chakra Exhaustion. Once this reserve has been depleted, the afflicted character will automatically pass out from their exhaustion. However, if they draw out too much chakra during this state, they can die. Details to all of this can be found below.

## Jutsu Cost

All Jutsu, no matter their type, have an exact cost to them. This is a list of the cost of Chakra when making use of regular Ninjutsu.

* S-Rank: 15 points.
* A-Rank: 7.5 points.
* B-Rank: 4 points.
* C-Rank: 2 points.
* D-Rank: 1 point.
* E-Rank: .5 points.

The cost of a jutsu is halved when it extends into a following round. In example, a shinobi uses Blade of Wind, an A-Rank technique. This costs 7.5 points to initially activate, when halved the cost equals 3.75 points. In situations such as these, we always round up to the nearest half or full number. This would make the continued cost, when used consecutively, exactly 4 points per round.

## Auxiliary Chakra

Auxiliary Chakra refers to the second, and final amount of Chakra a character can normally tap into during the course of a session. It is brought into play once the available amount of points from one's Chakra attribute reaches zero. At this point, the character begins to suffer from Chakra Exhaustion, and must make use of their backup chakra to continue fighting. The exact amount of Chakra given is exactly half of a character's total Chakra score. In example, if a Genin were to have eight points in their Chakra attribute, then their Auxiliary would be worth four points.

### Chakra Exhaustion

Once a character taps into their Auxiliary Chakra, they begin to suffer from the effects of Chakra Exhaustion. This creates a debuff that will severely hinder their ability in combat, affecting the rest of the Power Score negatively as each other stat is subtracted from by 2.5 points each. This makes them weaker in every sense of the word, leading them to be more susceptible against enemies while in this state. Below is a set of two Power Scores, showing the effect of Chakra Exhaustion before and after it is applied on a Genin character with rounded-out stats.

As you can see, this is quite a burden on the average character, knocking a Genin's power within the range of an Academy Student's. Because of this, it's important to avoid exhaustion where possible. And for those that do, to be extra careful what they do for the remainder of their fight. If they continue to exert themselves beyond their limits, they can potentially make themselves pass out. For those that go above and beyond in this effort, can even find themselves killed from this.

#### Knocking Out and Death

Once a character reaches the point that they run out of Auxiliary Chakra, they will have exerted themselves so much that they will naturally pass out. This is done as soon as the limit is reached, most frequently meaning that the character in question may find themselves passing out during, or after, using their Jutsu. The exact amount used does not have to equal what Chakra remains. However if the number is far greater than what remains, this will lead to the character's death. This is only if the amount drawn out exceeds half of one's auxiliary chakra.

In example, a Jōnin with 18 Chakra is terribly exhausted from a long fight. At this point they are well within their Auxiliary Chakra, and only have 3 points out of 9 points from these reserves. Despite their instincts warning them otherwise, they decide to attempt using Rasengan to finish off their enemy. Rasengan being an A-Rank Ninjutsu would cost 7.5 points, taking away from their remaining 3 points and exceeding the natural limit. They perform the jutsu, striking down the enemy, but at the cost of their own lives as they went over the maximum of their limits (4.5 out of 4.5 points). They naturally fall into a dreamless sleep, never to awake again.
