For the companions, can they join the combat? Or is there a toggle that I haven't found yet?
Not in the current version, no. Maybe that will be implemented in a later build
Oh, cuz I find it quite funny and awkward at the same time when they're just standing there while I'm blasting catastrophe against a poor lvl 4 critter or getting my sh*t obliterated when I first entered the church grounds 😂
