I just stacked boxes to jump over the wall of priestess gut’s room to get all the powder and oil barrels and everyone carries 3 or 4 depending on what their capacity is, and if I can’t clear a battle normally I reload to the save before and sneak barrels strategically around and blow them all up from a distance.
As such I don’t feel like there is a right or wrong way. Next play through I’m going to try not to do this but I know I’m inevitably going to try to come up with some really dumb cheese tactics.
Goblin camp you can just let gut drug you and dialogue then done. The drow what’s her name you can sell out the Grove and then shoot the bridge down as she’s leaving. The other guy you can void ball him into the pit next to his throne after the cutscene that makes him sit and invis or tp away with a scroll, or barrel bomb the whole room so no witnesses are left.
