The mod adds ability to dual-wield weapons in the game.
You can purchase a weapon you can use in your off-hand in Imperial City Market District in a shop called "A Fighting Chance" (check the armor tab).


How it works:
Basically the off-hand weapon is a shield with sword's mesh so don't expect to be able to attack with it, although certain power attacks and normal attacks do make it look like you're attacking with it, which is nice.
Also, since it's not really a weapon, it doesn't have a damage rating or anything. Instead it adds slightly to your weapon skills and attributes so you'll do a little more damage with your normal weapon which gives the illusion of actually having two weapons.
Now, I didn't really spend too much time on balancing it, but your damage should be somewhat equal to having a two-handed weapon (a little less actually, but faster attack speed should compensate for this too).
Warning: Don't drop the sword after you've bought it, you won't be able to pick it up again.

Pros:
- Dual-wielding is cool!

Cons:
- Ok, so the sword mesh looks ugly if you look at it close enough (or not that close :P). Let's see you make a better one in 20 minutes without NIF importer :D
- Damage may or may not be as good as with two-handed weapons.
- Only one off-hand weapon available, I'm lazy and someone will probably make better mesh for it and other weapons soon anyway or a NIF importer that works, go figure :P
