I am making a Battlemage and i would like to know how to build it correctly. Here is my question,would it be a good idea to have Strength on 20, dexterity on 18 and max melee and dodge out?
You might also want to pick up gloves of dexterity, +2 Dex, to take your dex to 20, thus giving you the bonus speed. Double damage is nice, but only get it if you need it.
I'm going to agree with loo here - try to be as original as possible. There's no 'correct' way to build a character. It's totally open ended.
