Average Manatee it's funny you bring that up because I originally joined the Codex to argue for a build like
Stoned Ape's Wolj here except on Octavia with R4/W3/AT10. As now it was
Daidre then who was telling me how ridiculous it was.
But then he was right because those extra 3 Rogue levels were a major price to pay that seriously delayed her development as a caster, as I belatedly figured out once I started suspecting that my dips and splashes were doing more harm than good and let her develop naturally. That's not what I'm saying on Sos. The price you pay there for letting him fight is much smaller and the payoff much bigger because he's 3/4, your only 2-handed companion, and has several spells and abilities that make him relatively effective at it.
Now the other thing I was arguing for then (and now as with Sos) was letting her fight with weapons when not casting, which is a much tougher case to make for Wizard than Cleric. But there was a very good Unfair player on Steam who tested the R4 build vs his R1 caster build and decided the R4 wasn't worth it but that even his R1 Octavia could fight with weapons to save casts (to his surprise). That's much less necessary in Wrath where you have a lot more rest available but
Daidre has already said he likes low rest so I'm surprised he hasn't discovered melee Sos himself. Casts-wise you're just using Divine Favor to offset 3/4 BAB and spiking with one cast of Divine Power/Righteous Might on the hardest fight each rest then making use of Frightful when you get it and whatever good Glaive you've got laying around.
