DDI Character Builder question, Customize buttom for equipment

1 post / 0 new
Hey, the game that I've been playing with recently, one of the characters got recieved a weapon that for all intents and purposes is a longsword (She's an eladrin shielding swordmage) that has reach 2, 1d8 damage, +3 Proficiency, 1d8 critical per plus, Vampire Killer(She deals 1 d6 extra damage to vampires) +3 enhancement, and it deals radiant damage in addition to regular damage. I'm using a radiant +3 longsword as the base weapon, and I was putting things in as notes, but was wondering how augumenting works and if it would be helpful, how do I augument the weapon?
