Hmm, perhaps we need to define charisma. The Oxford English dictionary gives this definition of the word. I'd give the unabbriged definition, but it is rather too long to type here;
charisma n. (pl. charismata) 1 a The ability to inspire followers with devotion and enthusiasm. b an attractive aura, great charm. 2 a devinely conferred power or talent. [eccl. L. f. Gk. kharisma favor f. kharis favor, grace] 1 see appeal n. **4.
**Though she is but an inamimate polygon mesh, she appears to have achieved definition 1 a, and though definition 1b could be shared by more than one person, most would agree it is largely relative, and as such,  is not applicable here. If this is the case I'm afraid there is little use in asking for help here,  as a man convincved against his will is usually a man not convinced. I could type the definition of the word appeal, but it too, is relative, unless you meant one of the many other defintions, in which case, I'm afraid I've misunderstood you alltogether. You haven't given anyone here much else to go on, even if they were merchants, which seemed to be your intended audience. I suppose V4 will just have to remain uncharasmatic for you, or whatever you meant by that. I'm afraid we can't help you. This happens in life you know. Good luck in your search.
