First of all, it can be any class, kit, dual or multi combo you like. Of the legit combinations only.

I myself loved a lot, and always use as main character, a berserker human, turned into mage, at level 10, and maxing him in mage 30. I use grandmastery with both quarterstaffs and 2 handed swords. What is YOUR favorite class and what weapon combinations you create on it? You can name only one, and it can be any you like, provided that it can be played without hacking/editing/modding on standalone game. Even popular ones, like Kensai/Mage, Cleric/Ranger, etc.

Blade, based on number of times I've played the game [not necessarily completed it through ToB]. #2 would be Stalker and after that a toss-up between Archer and F/MU, if memory serves.

But the Blade, hands down in terms of number of hours spent at the keyboard - I'm sure I have spent more time playing a Blade than all other possibilities combined.

Bards are good. But what is the F/MU?

Multi-class *F*ighter/ *M*agic *U*ser.
