Ok, first off, I like to make characters that are usefull for soloing, as an example, my main character is a Paladin/Rouge with the rouge level half of the paladin level so basically at level 6 it would be Paladin 4 and Rouge 2. This, however, is not really important, as this is about a new character I want to make. I have decided to make a Combat Class/Caster class as the title suggests. I have decided I will either se a Wizard or Sorcerer and either a Fighter or Barbarian.
I'm Looking more towards a Wizard for the wide spell range and bounus feets. But I'm stuck on the combat class, as well as what stats would be a decent enough fo such a character, not going over 16. I will likely also be using a human character, but suggestions are welcome.
So how should I go about this?
