Might go without saying, but you max your int out ASAP. Int is to wizards as HP are to Warriors, only difference being that when our mana runs out we can still run!!! Also, it will be very beneficial to get an Increased Damage IV o V very early on. This will give you more bang for your buck. with 30k to spend these two ideas shouldnt be too hard to do. If you can, also look for Reduced mana effect items, for the obvious reasons, and increased range items/spell haste effect items, these last two will help a TON when you start quadding. Wish i could give you more specifics on the items, but seeing as Bazaar is very easy to search, you shouldnt have too much trouble searching for items with these effects/int boosters.
P.S. IMHO mana regen items are extremely over priced and are not as effective as other effects, especially with the new downtime regen. I would avoid these items unless you find that 30k is able to do ALL that i recomended plus mana regen...
