Each weapon in the game, whether it's ranged or melee, is "socketed" and can be customized inserting certain mod packs. We didn't get to see much of this displayed in the demo, but some effects of mods, ranging from added damage to wider damage cones, were described for us. One cool effect we did get to see what was how you could see how mods changed the appearance of a weapon in-game. Similarly, in classic Diablo style every piece of armor you acquire alters your character's appearance. The variety of looks in the final build should be positively dazzling, as the demo showed off at least eight different parts of the body that had unique armor bits for them.​
