Leveling Sage

[azurerogue]

I would drop Endow Tsunami / Deluge and 5 other points (maybe from freecast - or possibly Dragonology - unless you're actually using it to hit an important INT band) to get Frost Diver 10. It's not a great end-game skill - but it can be invaluable in some leveling situations. If you're going to be with the wizard 100% of the time, though, you can probably go with what you've got there.
