Thank you for your feedback. Sorcerers are well known for protecting themselves from mutations, so it is normal for them to look normaly. Also its alpha legion which isnt as "corrupted" as most other legions. He holds a sword with a sould of a slaanesh deamon traped inside it, which doesnt just enhance his psychic powers, but also affects his personaly in a rather drastic way. Much like froustmourne and Arthas, but with a different effect of actualy gifting pleasure and desire for more excesses.... This was the idea.
