User blog comment:Patrick x hunter/whick one of these nen abilitys are the best and or will work for transmuters/@comment-1843762-20150919185119

Love the creativity =3. However,.. Whilst I believe lava and ice is theoretically possible, the others you've said are not (I don't think). As for Razzar though, this would totally be transmute. Basically it's just a better version of Ren (or is it Ten? the surrounding yourself with more aura. Wait or is it Gyo? gyaaa you know it xD).
 * Ghosting - "Specialist" - You can't change the property of your aura to make your entire body not solid. It'd be specialist.
 * No Pain No Gain - "?" - Not a nen ability. Just a good control over your mind.
 * Forgiveness - "?" - Hmm this is a good one. Again, I don't think could fall into nen. How would you transmute aura into something that heals wounds. Unless its a medicinal plant scent or property. But then it's just using medicine :S.
 * Shadow - "?" - Shadow manipulation. Transmuting (nor any nen type except maybe specialist) could alter and control a shadow. To alter a shadow is to alter physics of light (and space to an extent)... You could transmute your aura to look and act like a shadow though! But to make physical blade would be conjure unless you want the same effect as Zeno's Dragon Lance.
 * So actually... this would be "Conjure & Transmute" or "Specialist" I think. If it's possible.

Sorry I don't mean to discourage. These are just my thoughts. I can't help but think of HxH nen abilities all the time. I love the series too much. What are your thoughts?
