Horadric Cube Help I've seen many refrences to "cubing" and (since I'm new to Diablo) I don't know what they are talking about. I do know that cubing combines items, like runes into runewords, or gems into perfect gems. Can cracked/chipped/flawed gems be combined to form better gems? (can those gems then be combined?) Can low level runes be combined to form higher level runes? (and those combined to form HR's?) If I party and all the Act II quests get finished (without me participating in most of them...) how do I get the horadric cube? Thanks in advance!
