You made a SI build, didn't you?
What does SI stand for?
Build strength in Underrail is measured by how few consumable items you have to spam to get through.
I'm getting the feeling that stealth crossbowman is the opposite of this mindset. Elemental bolts, grenades, traps, adrenaline shots, you name it, this guy uses it. Was the reason why I picked it tbh – with psyker, I looked at all those things with "meh, more garbage, I resolve 90% of encounters by throwing in rage, then picking off the straglers anyway". Wanted a playthrough that made me use all the tools that are provided to me for once.
I also invested heavily into pickpocketing because I never did before, just to see what it's like, and it's fairly amusing. The value of the garbage you steal is usually zilch (though you can stop caring about ever running out of health hypos. It ain't gonna happen. Every asshole in the game has like three of them), but it's pretty fun to sneak behind some asshole, steal his ammo or drugs, and then initiate the fight, in which he basically falls flat on his face because you just stole all the things that made him dangerous.
