“Like many things about J’Rhazha, his sword is an illusion. Perception is sometimes more important than function.”
I’ve never been a fan of the idea that wizards not only are bad at using swords, they cannot use them at all. It’s even stranger to me that they’re allowed to be proficient with daggers and staffs, which strike me as much harder weapons to master. You can give someone a shield and a sword who doesn’t have much fighting experience and they’ll be able to bang away with the sword and block a few blows with a bare level of competence. I’m not saying that they won’t be killed by someone who knows what they’re doing, but actual proficiency with a staff as a combat weapon (beyond just trying to hit someone with a long stick) or knife-fighting or knife THROWING is a completely different animal. It strikes me as easier for a wizard to awkwardly flail at a foe with a medium length piece of relatively light-weight and purpose-balanced metal than knowing how to lithely move in for a killing blow with a dagger.
The other point I bring up in my argument in favor of wizards using swords is the number of magical swords showing up places. I can see a wizard making a magical weapon for their own use and protection. I can’t see wizards making a surfeit of powerful magic items that are of no practical use to them. Sure, you can argue that maybe they wanted their lieutenants to have magical weapons, but I’d think wizards would want to keep their edge and not make stuff that could be turned against them, especially not in the bulk you see in typical fantasy settings.
I would also point out that the difference between a Fighter’s combat ability with weapons and a mage’s ability is reflected mainly in THACO: the level 6 Magic user flails his weapon about with the same competence (THAC0 19) as a level 2 Fighter. Surely this should be enough to fairly represent the differences in ability without having to say that all wizards would either turn their nose up at wielding a sword or, holding one in their hand, would stand there and say “I just can’t use this. I mean, if I had to get significantly close to my opponent to attack with a short blade, maybe, but I – Oh, god, you’ve stabbed me while I was holding this sword and not using it!”
But this is AD&D and I’m not going to press the DM on the issue. Instead, I’m going to adapt it to the character.
As a Rakasta, J’Rhazha comes from a warrior background; it would not be unexpected to see a Rakasta wielding a blade, and a Rakasta wielding a blade is not someone with whom you would want to fuck. But this Rakasta is an illusionist and trickster (maybe even a coward), not a fighter. But he likes to maintain the illusion that he is.
