Special bolts which have no cooldown so you can stun as many enemies as you have ap
With a 100% chance to hit, maybe.
Which is something that never happens. I put as many points as possible and had 10+ perception by the time I was at Foundry. Hit chances ranged from 50-80% depending on circumstances (of course 95% for stunned ones).
You just miss, it happens. And when it does early in a combat against 4+ opponents, that's likely enough to get you rekt.
I mean, just do the math here, how many bolts can you fire per round? 3-4 in the first round, with drugs and the ability that gives you a freebie. One less the rounds after that. You have five enemies (at least). Even if you hit all the time (which won't happen), one will advance normally and the others be immune to stun the next two rounds after being stunned. Then what, set them all on fire? Again, would have to hit every time and even then, it's just a 50% chance. Tranq bolts, sure, but they do have a cooldown. And enemies heal themselves, too.
You'll have to get exceptionally lucky the first 2-3 rounds or you just won't win.
Except if you manage to even the odds with traps and/or grenades.
Bolt quivers are pretty useless tbh. 3 AP reduction isn't worth much (29->26AP and you have 50AP, normally) and other belts give you more slots.
Again, I'm not saying it is not possible - I did it myself, after all, it's just annoying as hell to play.
But compared to other builds, it's much harder and riskier.
I'd bet I could hit a several m² large mark on the ground a few meters away..
During life or death combat? Not unless you're a highly trained/conditioned professional.
Bullshit.
If you have the time to arm and throw a grenade, you have the time to aim at least somewhat. Seriously, we are talking about less than 10m here (which would put you in harm's way realistically, but explosives in Underrail have kind of a small radius), and you have to hit a spot roughly 3x3m, not anything far away or hard to hit in any way. I wouldn't know how to properly arm a grenade in the first place, but I could sure as hell throw it to come down
roughly where I want it to within that distance, not twice the distance away or landing right in front of my feet like what happens in Underrail.
Also, grenades in Underrail explode on impact, they don't roll around to explode after some time. The latter would indeed make more sense, you can't fully predict how something will roll even with lots of time, but that's not what happens.
The Underrail situation is more akin to throwing a rock or small&heavy ball at a sports event - aiming-wise, anyway.
Besides, a character in Underrail
is a highly trained professional - but even with a comfortable score in throwing, your grenades still end up all over the place.
