Skills-wise, if your looking to go Archon you might want to ditch Magic Missle for something which will get you back into Archon quicker - like Living Lightning. The damage sux, but it will proc CM more often. As for gear, it looks like you have enough Life. I'd work on building that DPS figure if your looking to move up a monster power or 2 for farming. Not sure on your budget but you want to build up Crit chance, crit damage and attack speed. Things to look for: Witching Hour (Belt) Lacuni Prowlers (Bracers) or crafting your own Inna's temperance (Pants) Zunnimassa's Trail (Boots) (If used with a black weapon) A triumvirate (off-hand source) might also benefit you. You don't really need to go the Chant's set if your not going Freeze Wiz.
