Pyro secondary : Chenosalt (Name sake : nitromethane & hydrazine salt)
Expands primarily ammo(fuel) capacity by 50%
Unable to pickup small ammo boxes.(Mainly due to the weapon's gimmick)
Throwable like the gas passer, consume all your fuel at once to create a time bomb.
The low your remaining ammo is, quicker the detonation is.
Upon consuming, you lose 100% of your max ammo. Meaning you can't even refill your primarily from picking the ammo boxes. After 5 seconds the first ammo you pick up restore the capacity. The damage ranges from 1 sticky equivalent to 6 sticky equivalent, depending on your remaining fuel. Lowering the remaining ammo makes the explosion more devastating.
He actually shakes it before throwing it, making a huge delay for the weapon to function.
Promotes Spycheck for wasting the ammo.
The default tank is replaced by the weapon's new model (without certain cosmetics that overwrite the tank).
(I'd rather balance gas passer by changing it to an area denial molotov cocktail. I prob omit the "wet" function too. This weapon might hinder the current GP tho, I think it's balanced.)

Spy melee : Assiner (Name sake : Ass + sinner + assassin)
Only able to backstab while airborne, grants higher jump while deployed. Disguising as faster classes (include Pyro grabbing powerjack, demoknight forces 0 head state.) adjusts your speed to match the opponent. (no need to deploy the weapon) Excessive speed gained from the knife consumes cloak meter. Jumping while disguised consumes cloak meter too.
The main purpose is to disguise yourself as a scout to get the advantage of faster movement speed. Promote vertical trickstabs by allowing him to jump off people's head more easily. Makes him mobile. But the downside is pretty serious. For those not liking the dead ringer, or being cloaked the whole match.
Minor states ; Negate fall damage for successful backstab.

Medic melee : The paper
No damage weapon. Upon hitting the enemy, mark the enemy with "convention" state.
If you are the one marked for it, killing the medic results in loosing your ability to attack for 7 seconds.
Visual : A paper with different styles available. Medic slaps enemy with the paper.
Last ditch weapon for a self-preservation. Might help teammates as well. Medic has to risk his life for hitting the melee on target. High risk high reward weapon. Probably better healing nearby teammates.
