Get Skeletal Wall (16th) to summon blockers that actaully do damage ! This spell has been awesome for my Survivor (Archer/wizard with sword too, heh). Its not actually a "wall" but a spell that summons 5 skeletons at once. They then move around to attack anything dangerous they see. You can run away and lure monsters back to your waiting skeletons (skeletons dont follow you).
While your blockers are distracting your foes, you can be using spells and then switch to a bow to do damage, when you want to save mana. If you need an extra kick, poison the arrows (skill) and spread the hate around.
At 16th you can also get the skill to reflect all missle attacks. I have heard that it works so well you can pretty much ignore archers like steel archers, but I dont have the skill (didn't need it).
I currently have 35 minor restoration and 15 restoration potions, and I dont use them fast enough (most battles never use 1) I leave herbs on the ground all of the time.
I cant give much advice on playing a pure wizard type as the only elemental-type spells I use are freeze and lightning (deadly disks I didn't like). I find archery and the occasional two swats from a 75 damage bastard sword, is all the mana-free killing power I need. Only need around 45 STR DEX for these.
