Thanks man ^^
Boil Release is a gas element that combines Fire and Water. The version I will be using is a corrosive vapor that has even been shown to melt away Susano bones. The gas can cover a long-range shortly in the time since it's a gas.
The advantage is that it can melt pretty much anything including as said Susano bones. Custom wise it can be formed into any shape and can control how corrosive the gas is as shown as Mei could control. The user is also immune to their jutsu. It is also netural to lightning and Fire jutsus.
Disadvantages are that in an open space it can be hazardous to teammates so it's better to use it when it's 1v1 and not 2v2 unless your teammate has a defense to protect them. Wind can easily blow away the vapor so it is weak to Wind.
Nice. You touched on everything I was looking for. It's especially important to note how hazardous it can be for your own teammates. For you, who fights with a snake and bee summon with you at all times, keeping track of your animals and ensuring they're not in the path of your own attacks is vital (unless you willingly want to kill them for some reason).
The boil techniques you can learn are listed below. Explain how they work, and ask any questions you might have.
( Futton: Katakiri no Jutsu ) - Boil Release: Solid Fog Technique
Type: Offensive/Supplementary
Rank: B
Range: Short - Mid
Chakra cost: 20
Damage points: 40
Description: After performing the Snake hand seal Mei will release from her mouth a large amount of Vapor that rises up to her chest and spreads out around her that creates a blanket of corrosive fog that can cause severe damage to her target by melting some of the targets skin but like the Skilled mist technique doesnt have full acid properties.
Note: Can only be used by Mei Terumi
( Futton: Kōmu no Jutsu ) - Boil Release: Skilled Mist Technique
Type: Offensive
Rank: A
Range: Short - Mid
Chakra cost: 30
Damage points: 60
Description: After performing a single hand seal the user creates a cloud of mist from their mouth. This mist has corrosive properties that is capable of even melting the exposed bones of Susanoo. The technique has an inherent disadvantage in that its effects are indiscriminate, limiting its usage to areas that do not presently contain allies until the attack is completed. Though the mist is corrosive to all around it, the user seems to be immune to it, but the corrosiveness of the technique merely can cause some severe damage to the body of the target but not have full acid properties that could melt them instantly.
Note: Can only be used by Mei Terumi.
(Futton: Tsumibukai Renge) - Boil Release: Sinful Lotus Technique
Type: Offensive
Rank: A
Range: Short - Long
Chakra cost: 30
Damage points: 60
Description: Mei manipulates her chakra to create vapour to be released from the ground that she then causes them to create corrosive explosions. the corrosiveness of the technique merely can cause some severe damage to the body of the target but not have full acid properties that could melt them instantly.
Note: Can only be used by Mei Terumi.
