User blog comment:Patrick x hunter/some nen ability's do not work/@comment-27459426-20151224000927

I think everyone Is approaching this in the wrong way. I somewhat agree with everyone who has posted so far, however, I also disagree with some of it as well. In regards to a poison gas its actually an obtainable feat. for a transmuter. Like everyone's said the user would have to undergo training like Killua did and expose themselves to poisonous gas in non lethal doses. This is more than likely possible do to the fact that some gases can be felt on the skin like steam or smoke. The same would go for ice although I would place it under the Transmuter category since the training would be fairly simple. One could start by freezing their finger tips and slowly work up their body. The hardest part would be the head since if you wanted to encase your body in ice armor, you would need someone to assist you and break the ice before you reach a dangerous temperature. I don't see a need to spend years in a snow filled land when you can take an ice bath instead and not have to waste time. I'm sorry I just don't see why it's a bad thing, either, that you'd have to spend years for it to work properly. Bisky told Gon and Killua that the rest of their lives would be spent refining and practicing their abilities to perfection. This is also shown in great length by Netero who spent decades meditating before even developing the ability he came up with based on repetetive routine. I will agree that there are some outragious abilities being created by fans, although I see no reason why they can't actually work with some direction. If anyone would like to discuss this with me I'd be more than happy to put my own nen creations on the line as examples of practicality.
