BLIZZ ABS HOW TO ADD WEAPONS THAT CAN BE USED IN COMBAT?

After millions of try's of trying to install this complicated thing i finally got it working and set up with my game. Now i want to know how to add weapons that the player will smack enemies with or shoot enemies with? Take this game called project viral (uses blizz abs) for example the player equips a weapon and hits enemies with it in real time i want to know how to the add weapons to my game and into the players hand? With having the players weapon actually show up on the game do i have to sprite the animation or what?
