So, I went with a Staff Magus for a game and am about to rapidly level from 3 to 6 thanks to a deck of many things. I chose this build knowing that it was not an ideal build (crit fisherman)... but someone pointed out that with wand mastery, you could effectively dual weild with a staff in your casting hand, so I'm wondering if there's a way to make it work. I realize this is a situational - when you have a magic staff (not yet) and are specifically casting from it while full attacking, or else not casting at all that round (so far, at the low levels that seems to happen a fair bit.)
So far, I think the major problems are flexibility (dropping / putting away your off hand weapon when you want to cast the old fashioned way) and of course the two-weapon fighting feats AND the additional penalty to two weapon fighting + spell casting.
I want to ask though, is there any way to use this to my advantage realistacly? I'd assume that even with the feat, a quarterstaff still isn't a light weapon.
Didn't see why you want the quaterstaff to be a light weapon.
As Staff magus you can wield the staff one handed (thanks to Quarterstaff Master), so you can use your other hand to wield a wand, cast a spell or whatever.
Only "issue" is that you have to decide at the start of your round if you wield the staff with one or two hands.
Also you can get quickdraw or a magic quiver (or flavour change it to "wand holder") to draw the wand as a free action.
I was more looking for advantages to use as opposed to the traditional magus builds. So far, the only real advantage I can see is shield bonii vs. armor (you can sleep in light armor, so it's more convenient) and that a normal Magus would have trouble finding a hand to carry a staff in. I'm trying to figure out if there's any tricks I can pull using this archetype in particular though.
