Greetings,
This will be my first AoC exploit/bug/.. or however you want to call it, which I found while playing my ranger.
This "bug" contains fighting with both of your weaponsets, however, the damage does not stack(=useless). Meaning it'll be for the looks.
OK, here's how it goes.
First and for all, equip two weaponsets. (a bow and a xbow, 2h and 2x1h, etc..)
Now, in order to do this, you will have to attack a mob and at the time your weapon is about to hit the target, switch between weaponsets.
e.g.: I shoot an arrow at X, but just before my arrow hits X, I switch my weapons.
-> I'm now equiping my second weapon (crossbow) with my bow. However, as I said before, the damage does not stack, so the only thing that's going to do damage is my crossbow.
With some weaponsets it looks pretty cool, so have fun with it.
Feel free to flame.
Oh yeah, one more thing: I only tested it with a bow and a xbow, and 2x1h and a 2h.
