User blog:Jojo-a-gogo/ What would your nen ability be?

I already asked you what nen type you'd be now you got to come up with an ability.

I know I said I'd be an enchancer but it'd really want a transmutation ability. I know it's gonna sound really OP, it's not that original and it's a little gruesome but I'd want the ability to transform my nen into a deadly airborne poison that rots people from the inside out when it comes in contact with them. For safety, I'd probably conjure some sort of armor that would prevent the poison from harming me. I also can deactivate the remaining poison in the air at will. It's a pretty wide range ability like Feitan's "Rising Sun".

Tell me what you think of it and what would your nen ability be?
