Mage school with a warrior

[KongMysen]

First of all thanks to anyone contributing to newbish questions. Its rarely seen on a game forum, that ALL "stupid" questions deserve the same mature and construktive replies.
I just registered this forum, but I have been reading some for about a week. I played KBTL with a normal mage, and replayed it with a mage on impossible.
I mistakenly thought KBAP to be just a 5-hour expansion, so I chose impossible again. This time as a warrior. Stupid me, since I have been struggling alot so far with a huge lack of gold. Troops have changed, the pet is new. New spells etc.
I would've had a more fun playthrough had I chosen to learn the game on Normal difficulty instead. I have been using Marauders forever, because of my lack of gold, but I finally started a no-loss streak due to finding some red dragons for sale.

My skill-tree build has become randomized. I simply dont know where to put my runes anymore. The warrior and mind trees are pretty straightforward, but i simply cant figure how to place my magic runes.
I'm level 20ish and so far I have maxed Distortion, 1 point in Order and 1 point in Transmute. I bougt the Ancient Amulet (4int, 15 mana and 10 runes after 50 battles), just to give myself some magic power but primary for the runes.

I have i few choises. I could ignore Chaos and Order completely and focus on getting myself some more mana and intellect. However i dont know whitch spells lies in these schools. Its unlikely that I'll be using Damage spells ever except Trap, but Chaos might be holding on to some strong Non-damage spells... Is there still a Sacrifice spell, and is it as crucial as I found it in KBTL?
Does Order still provide a resurrection spell?

Should i build a more powerful warrior-mage, og a more vercatile warrior, who can master alle spells in all levels?

Btw. I have NO useful items yet except the Ancient amulet. I have been saving my cash, so suggestions starting with "it depends on your items..." arent really useful

I'm open to suggestions. I would hate getting stuck again in 10 levels simply because I choose wrong

Thx in advance
