So I re-watched the Dragon Age 2 destiny trailer (Found Here: https://www.youtube.com/watch?v=jlACgYHtWCI ) and I wanted to figure out how to make a character who fights like that. My initial thought was making a staff magus and either flavoring a normal quarterstaff to have one end with slashing damage or making an exotic double weapon with one end slashing and one end bludgeoning and saying any effects related to quarterstaff apply to this weapon. This makes sense in reality but it requires some house ruling.
The other option I thought of was making a normal magus but get the eldritch heritage: arcane feat at third level and making the arcane bond a guisarme or something. This would be mostly rules appropriate but requires a number of factors, It requires that an arcane bond can be used with spell combat (can't find rules saying yes or no specifically, it says light or one-handed only but the arcane bond could fudge that a bit, its interesting). It also requires that a magus can spell strike with a two handed weapon(again can't find the info) this might require less house ruling but it also feels more trolly and rules bendy.
What do you think? I think the first option would be the most balanced but it does require house ruling.
