Encountered one on a previous playthrough. After that one, I made sure to keep the freaking containment doors shut forever. It wasn’t that hard, but figuring out a plan on the fly was tedious.
So first, I had a nodachi and good skills concerning the weapon, plus I had ninjutsu. If I do a critical hit, I’d do around 130-150 damage, allowing me to slowly chip at it despite its regeneration.
On the other hand, I wasn’t sure if it was due to being stunned since it was moving erratically, or I’m swinging the nodachi hard enough to throw him a space away. Either way, it pretty much meant me having to walk to it, leaving my crits null and void thanks to that, plus the fact that non crits can go as low as 20 damage.
The disector would do some damage, but once again I had trouble with the nodachi tossing it around. It’s been stunned so much I haven’t even taken a lot of damage at all. A few dents in some of my armor, and that’s about it. I tried making it go slower by luring it around the tables, but it still kept moving erratically.
So, I went with my last idea. Pin it next to the second containment console. Just to be sure, I moved some chairs around that area in case they’re needed. Dragging the chairs took some time, but since all I gotta do is hit it a couple of times and it’d just waddle around and not attack me, it was easy enough. Then I lured it to the spot, and realized that adding a locker would be better.
The setup was this: console, to the right of that is the chair and the shoggoth, which I eventually put in that spot by randomly hitting it with the nodachi. Above the chair and to the right side are walls. Below the shoggoth is my player, and to my right is a locker.
Since it’s trapped in one space, I can hit it without having to move around. Just to make sure, I fire up the hydraulic muscles CBM and light the chair up with the mini flamethrower. It took a ton of hits to kill it after that, and only after a lucky break with multiple crit hits in a row.
I may have had an easier time if I used some meth, as I came across some on the journey to that lab.
But seriously, after that encounter, those doors stay closed. Freaking closed.
(on the other hand, my current playthrough has my new character based above ground on a lab. I’ve been liking that lab base, and soon enough I’d like to clean the lower levels)
