I chose Cipher ranged but it seems weak and I hate having a shit ton of party members. Anyone got a strong build that doesnt require a full party? 4max?
Rogue, max out might (20ish if you're human and shit) (later on sleep with hookers and crap like that for massive bonuses)
19-20 dex
Rest 10
Dual wielding, take all the passives that boost your damage, dual wielding specializations (+attack speed), passive crit boosts and that "finishing blows" thing when you can. Importantly, take the blinding ability first - it lets you instakill pretty much anyone for much of the game because you get sneak attacks against blinded people. Take the ability that lets you turn invisible when targeted.
After that it's about finding good gear. Enchant some stilettos and find the stiletto that casts "Jolting Touch" or whatever on hit. It seems to do like 70-80 aoe damage whenever it triggers, and because you attack fast, it triggers more, so even against enemies that have massive DR you'll be doing tons of damage.
And as a rogue you'll have traps and all kinds of stuff. Stack up on scrolls and potions just in case.
Playing on Normal and I could very likely solo 95+% of encounters (70+% without pulling any trap tricks or using consumables), I have a party of 4 but because 2 are casters I usually leave them out of most fights (takes longer to micro them than to finish the fight with the rogue) and kill enemies with my rogue while my fighter tanks.
My first rogue was fucked because I was still in D&D mode and took like 12 might and focused on dex and perception. This rogue has been destroying stuff from day 1. My main's done something like 14k damage so far, my fighter has done 3k and then a mage and a priest have done 0.5-2k.
Oh yeah, and you can initiate fights with arquebus sneak attacks. It's enough to insta kill one enemy quite often.
