I found hybrid rogue/warrior completely useless build, but maybe i was wrong. Battlemage was working pretty well for me, rogue-mage wasn't so bad, but rogue-warrior... Any tips how to play that hybrid?
No tips, figure it out yourself. Thats a more rewarding experience.
Its a fighter-rogue-witch-mage kind of a build actually. Currently. - And i dont use sneaking and backstabbing at all.
I just dont even think about classes in OS.
Thanks for the responses. I guess my original question was aimed at whether or not the "double attack" was real and whether it only worked with daggers. I was hoping to try out a double attacking sword or axe character, but it looks like that wouldn't work

And it shouldnt. That would be too cheesy and turn the game into a farce. OS is a tongue in cheek fantasy but not of that farcical kind.
Two daggers - with double AP cost, that would be appropriate. And much easier to do since the animation is basically already there.
