Gasses, weapons, and armor!

Name: Fatigue
Rank: B
Application: Gas (Color=purple)
Range: 10 meters
Effects: The user breathes in the gas through the mouth or nose. The gas begins to infect the opponent causing them to feel less powerful in terms of strength. It infects their brain into them thinking they are getting tired and need to take a rest from working. The brain begins to tell the muscles of the user that they are tired and need a break, causing soreness and loss of strength and speed.
Turns: User breathes in the gas and after 1 post of initial contact with the gas, they begin to lose strength and speed over the next 5 posts. The opponent will begin to lose 3% of both speed and strength per post. For 2 posts after losing speed and strength, they will remain that having that loss. After 2 posts, they gain back the speed and strength in 3 posts time, 5% per post.

Name: Blood Flow
Rank: A
Application: Gas (color=red)
Range: 15 meters
Effects: The opponent breathes in the gas through the mouth or nose. The gas is breathed in and combines itself with the oxygen in the lungs, thus going into the blood stream of the opponent. The poison begins to infect the red blood cells and slow them down at a rapid pace. The slow flow of blood begins to take action in the user, causing varying effects. The body will then begin to have a difficult time breathing, having a normal heart rate, slow brain activity, the ability to make intelligent choices to get to safety is sometimes a side effect.
Turns: The opponent breathes in the gas in post and initially the brain goes into action. The blood flow of the opponent begins to slowly decline to dangerous levels after just 1 post. The effects of breathing begin to set in, causing the user to feel fatigued and slow down. The opponent is slowed down 30%. The heart rate then takes action, making the user feel numbness to their limbs where the blood flow is decreasing. After 3 posts of coming in contact with the gas, the body’s organs will begin to shut down, IF the opponent does not stay mobile. Meaning, the sufferer from the gas MUST remain in motion for all 3 posts. Few have been known to survive after 5 posts of initial contact without remaining mobile. The gas is worn off after the fifth post, if of course the opponent is not dead at that point.

Name: Colors
Rank: B
Application: Gas (color=rainbow)
Range: 10
Effects: The opponent breathes in the gas through the mouth of the nose. The gas then infects the brains ocular section where it infects the eyes. The eyes then will act as if they are completely color blind, shutting down all loss of color in the eyes. After a short while of being color blind, the gas causes the brain to overload the eyes with colors, not being properly told what to see specific things as. The eyes will then be portraying colors to be switched around. This comes from the brain not allowing the eyes to know what is properly being seen as what. The overload of colors changing so rapidly causes the user to become nauseous and get queasy. Some have been known to get massive migraines from the change in color and dizziness.
Turns: After 1 post of initial contact, the opponent will become color blind and not be able to see any color for 1 post. After that 1 post, and lasting for 3 posts, the colors the opponent sees will begin to have them changed and swapped rapidly for all 3 posts. The colors will begin to settle after those 3 posts and return to normal.

Name: Angel’s Grace
Rank: S
Application: Gas (color=white)
Range: 5 meters
Effects: The user will breathe in the gas through their mouth or nose. This gas is possibly the most unique gas in Iris’ arsenal. It acts unlike any of the other “poison.” The gas acts as a white blood cell to any sort of poison that has already infected the users system. The gas travels all over the body and reaches into the heart, transporting the gas into the blood cells and spreading them all over the body. It infects the brain, taking out any sort of infection that may be going on their along with the lungs, and other internal organs. The gas heals any sort of infection or internal bruising, bleeding, or injury that a bodily organ that the user may obtain in their body at that time. Not only does it heal them of any current infection, but it rejuvenates the body, giving them a 10% boost to specific stats on the person. The body becomes fully thrived in energy and makes them feel better, along with actually making them better.
Turns: After 1 full post of breathing in the gas, the user will begin to feel the effects of the gas. Over the next 3 posts, the user will begin to feel the effects of any poison or infection wash away from their system, up to A rank max. No S rank infections or poisons will be effected by this. During the 3 posts of feeling the infections wash away, they will also gain a 10% increase to speed, strength, and endurance increasing by 3% per post, and finishing off at 4% on the last dose of the gas. The effects of the energy burst last for 3 posts after the poison has been washed away completely. After the 3 posts of having the stat boost, they wash away completely and the body returns to normal function. *This gas does not heal any physical injury, such as burns or cuts, only internal damage*

Name: Gas Container x4
Appearance:

Spoiler:

Rank: C rank
Range: Gas leaks out into a 10 meter radius from the landing point of the ball.
Special Abilities: The gas containers are all shaped and colored differently to help Iris signify which is holding what gas she put in them earlier that day. The container has a circular button on them, when pressed it releases the gas out into a 10 meter radius in 2 posts. The ball spins and leaks out the gas at a rapid rate. The container has a delay 3 seconds after pressing the button as it lights up and beeps until rapid release of the gas. The technology Iris made this with allows the ball to be used in the dark, so she can know where the ball lands. Iris designed the tool to be large enough to hold a significant amount of gas along with the board she scrapped from an old radio to design a switch to have the light up effects along with the beeping.
Descriptions: The 4 special types of gas containers are a unique tool in the Eijutsu user’s arsenal. They are color coated and designed differently for easy quick use to differentiate which is holding which gas. They have a circular button which releases the gas as the ball spins on the ground. The balls are very small in size. They are small enough to hold in a small pouch on one’s hip and fit in the hand of the user with ease.
Origin: Iris designed these herself and customized them to her liking.

Name: Shin Kariforunia kyōwakoku
Appearance:

Spoiler:

Rank: A rank
Coverage: Full Body
Special Abilities: There are a few special things this armor has that most do not. The first is its metal vest that covers from the waist up to the neck and covering the back of the skull. It is very unique and adds some needed coverage. The main special ability it has is its mask. It is removable, but what is so neat about it is its use. It is similar to a gas mask, and obtains similar functions, but it has the use of allowing one to breathe in sand and other dust particles. The mask has the ability to filter out sand from sand or dust storms and release it while filtering in good oxygen for breathing purposes. The lenses on the mask are also quite neat, as they allow the user to see in thick sand or dust storms. The final added touch is the knee and elbow pads. They are very strong and durable, and can cushion a fall or an attack if used to deflect said attack or landed on for a fall. The armor is considered light armor.
Descriptions: Armor consists of denim pants that are slightly baggy to add protection along with mobility. The duster coat is made of strong hides and adds increased durability against attacks or blades. The back of the duster has the small air tank that allows the filters in and out of sand and oxygen. On the inside of the pants and duster are knee and elbow pads to increase protection. The metal vest that extends up the back of the skull is made of lightweight iron to allow mobility with protection. The mask and helmet are both made of the same alloy. The gloves are made of a thickly woven leather fabric designed by special light weight armor makers. The bracers are made of the same thick hides the duster is made of, along with the boots.
Origin: Iris was fitted with this as she was shopping in Sunagakure her first day there.

Name: Smoke Bomb Canisters x6
Appearance:

Spoiler:

Rank: C
Range: 10 meters
Special Abilities: The container has a circular button on them, when pressed it releases the gas out into a 10 meter radius in 2 posts. The ball spins and leaks out the gas at a rapid rate. The container has a delay 3 seconds after pressing the button as it lights up and beeps until rapid release of the gas. The technology Iris made this with allows the ball to be used in the dark, so she can know where the ball lands. Iris designed the tool to be large enough to hold a significant amount of gas along with the board she scrapped from an old radio to design a switch to have the light up effects along with the beeping. This container specifically is designed and works only with the Smoker Gas, Iris designed herself.
Descriptions: They have a circular button which releases the gas as the ball spins on the ground. The balls are very small in size. They are small enough to hold in a small pouch on one’s hip and fit in the hand of the user with ease. They are all smaller than the normal gas container for Ayaka, but only slightly. They are all also the same color, as they all only work with a certain gas Iris had made.
Origin: Iris designed and made these herself after working a lot with tools for her Eijutsu arsenal.

Name: Smoker (Shut up Bill!)
Rank: B
Application: Gas (color=dark grey)
Range: 10 meters
Effects: The dark grey and dense smoke is released from the canister onto the opponent. The gas seeps into the opponents eyes and irritates them to have the opponent crying and rubbing their eyes constantly. Along with that, the gas, if breathed in, can irritate the esophagus and lungs, having the opponent cough uncontrollably for a substantial amount of time. Sufferers from Smoker have been known to vomit a large quantity because of intense coughing.
Turns: On initial post, the gas begins to be released into the air. However, this gas is thick and dense like smoke, and most would think that is simply what it is. However, on the post after the initial placement of the smoke bomb, the gas begins to take effect on the opponent. The gas gets into one’s eyes, making them cry and have watery eyes. The eyesight is increasingly blurred because of this. If breathed in, the gas can irritate the esophagus and lungs, causing the opponent to cough uncontrollably. The coughing has been known to lead to vomiting from the opponent. The effects of the gas last for 4 posts. The smoke screen itself lasts for 3 posts.

One's body cannot lower it's internal temperature like you're suggesting here regardless of whether or not it is tricked into thinking it is too hot. So you're going to have to edit the effects of the gas.
