The good cue that they took here from lots of PnP rules is that crits are just a +50% to damage, no goddamn instakills because someone lucked out with a greataxe or scythe. Even though the dual health mechanics would actually have made that kind of thing more acceptable in Pillars; but it still sucks balls.
There are builds in the game that definitely allow you to oneshot with a lot of crits by stacking damage multiplier modifiers and hit to crit effects, you need to specialise for them though. Generally rogues and rogue multiclasses are the ones able to do it though. Due necessary passives.
