Haha, methinks you're pretty much set Bobb

As far as improvements:
- New Level 55 Charm - Preferably with 200+ EE, and of either Fire or Ice, so your proficiencies actually help it. It'd be ideal to get all of the same type charms, but that's pretty hard to do, since most of your charms are hard to replace/godly already in their own right.
- Better regen gear - The cap had been increased to 2 Regen per tier now right? Your old regen gear is kind of outdated then =P
- New Level 30 Heal Charm - Preferably Heal or Focused Heal. Not as much of a problem for later classes, but as a Mage, you probably wouldn't want to heal a 25 in the middle of an important Well battle with a 200ee Sword =P
- Better late-game weapons - Um.. don't think you really need this, with your godly Lvl0 weapons, but perhaps if you're really bent on upgrading somehow, you can get a higher leveled weapon with more Int, and perhaps another helpful mod like Mind Numb, the new Mana Skin, Mana Syphon, etc.
Good luck on casting all classes! Perhaps this season I'll be able to cast with something above Paladin
