Not to sound Nit-Picky, but with Wizards and casters in general, you want to spend all of your build points maxing out your primary casting stat (Int) then the rest into Con, with maybe two points into Strength, those spell components and stacks of 100 scrolls do get heavy with bags full of loot

Now... about funds for a +6 con item and/or a GFL item... and those sulfurous stones...
I recommend heading over to The Devils Battlefield, it's a rough place, and will take some practice, but you should be able to solo all of the quests, at least on casual/normal. Do not get frustrated if a couple of em take multiple tries, as you will need to find what spells are going to work best for ya, but they are prime farming grounds for you because....
There is a named belt with +6 con and GFL on it, Knosts Belt, drops in Genesis Point (will need a hireling here for lever pulling)
You can also get numerous Shroud components, small, medium and large from the 4 ToD flagging quests.
Good cash, good practice and good renown (if your in a guild)
Also, flagging for ToD and the ingrediants for Boots of Anchoring, which are needed for ToD, all drop in these quests.
Weapons Shipment - Another Shavarath quest, which, rarely, drops the Mysterious Bauble, which is great for all casters
