Kaseisekijun

Kaseisekijun is a unique living weapon. The green spikes protruding from the weapon is a sign of its extremely acidity, a byproduct of its extreme affinity for the kekkei genkai. It is able to utilize both the steam and acid variants of the nature transformation to devastating effect.

Abilities
Kaiseisekijun's main attribute is its extraordinarily intense acidity. The acidity is so extreme that it's acidic levels aren't measured by the, but by the (H0). The acid produced by this hammer over a dozen times as acidic as. The acid itself will rapidly and explosively decomposed when it comes into contact with water, making a massive and very focused explosion. Alternatively, the user of said hammer can produce extreme toxic vapors. It dissolves glass, organic material and even metals and inorganic materials. The hammer is able to take in from its surroundings, which it can use to safely create  chakra, while granting the user complete control over it. The crystals on the front of the hammer can be used to inject the highly corrosive acid into targets, spray the acid at foes and even fire crystals that will corrode anything they come into contact with. Alternatively, the crystals can greatly extend, allowing the user to impale struck targets. The jets on the back of the hammer can be used to propel the hammer forward for an exponential increase in force when swung. The hammer itself makes the user immune to its acid, allowing them to safely touch it. Consequently, anything that touches the wielder of the hammer will begin to corrode at an exponential rate.
