Additionally. if you want to, you in Wiz 8 you can use a Bishop who can master all magic schools.

If you don't mind repetition, you can power train things like stealth, magic schools, locks and traps, etc. since in Wiz7 and 8 secondary slills are "learning by doing" and many are transferable between character professions.

Anyhow, I shouldn't be touting Wiz on this tavern since it is way off-topic but I will add that there are four great mods now available for Wiz8 (and a great level editor is available for those who would mod the game - MadGod's Editor).

I am a dedicated M&M fan as well as a Wizardry8 fan as you can probably see (I did not not like Wiz1-7 very much and think MM1-5 were much better developed, but that's just an opinion)
