Is it truly possible though?
I feel like I'd die every 40 minutes, lol
It's totally possible. But it requires a first playthrough on hell mode at minimum to get the gist of the difficulty.
After that you must learn enemy weakness and pattern and come up with countermeasure. You must also learn how to build a wall and turtle formation/choke point with your 2 companions.
Most important is to never take risk, never rush in, even if your companions or kidnapped victims are being raped or in danger, you must not rush in at all cost, never put yourself in danger.
Only fight 1 on 1, if there're 2 enemy ganging up on you, you're toast, unless you bring a lot of stamina potions and manage to whistle your companions just in time to save your ass, effectively turning such a dangerous situation into your own ambush scenario.
What if you're in a tight corridor, there's one goblin blocking your path and a goblin archer firing at you from a safe distance ? There's 2 way to handle that, either retreat at full speed or seduce the archer to come into your range. Hint: Manage your weakness level to suit the raid and you can seduce almost any humanoid enemy.
There's a lot more advanced dirty combat tactics, but where's the fun if you don't experience it yourself.
