So is this fun, or dumb? I have a ftr3 / rogue4 who just leveled to 8 and I'm thinking about taking a level of wizard at 8, another fighter level, Wiz2 at level 10, and fighter thereafter.
He's a whirlwind and skirmish combatant, we have another melee in the party.
With those 2 levels of wizard I lose 1 bab, a few hp, slow down some fighter progression and fort saves.
I get +3 will, prescience 4/day, +1 initiative, always act in the surprise round, a couple of spells (true strike, vanish, enlarge person, and shield are all handy), and a crow familiar to make fun of my companions all day.
We are using feats and he did take the magical knack feat when I brought him in at 6th (replacing my now dead sorcerer). So he would some reasonable time out of vanish, shield, or enlarge person. He is a light armor wearer, so he would fail from time to time.
So, sounds like a bit of fun to me, or is it too big a hit on his melee capability?
whoops - meant to stick this in advice!
