Well I fucked up.
I decided I was ready for F26 boss... well I was but I didn't bring enough gear with me. I lost like 3 or 4 DM and all my armor.
That sucks, but at least it's over with, now for the next elevator. I go floor after floor, running out of weapons. I'm on F29 and check where I need to go next and then I notice that F27 did have an elevator and somehow I missed it (I had glanced at it and for some reason thought it was one of those side elevator).
Oh well, I'm already on F29 so quicker to keep going up... and there's a trap room with a reversal tuber. My hits do like 1% of its health while it just about one shots me with attacks that cover the whole room. I decided not to waste my last DMs in a futile attempt so I gave up.
Now I need about 115 000 kill coins which wouldn't be a problem if it wasn't 40 000 over my bank limit. I'm considering just killing the hater but she has several blueprints, rare mats etc. so it might be worth the coins.
