During one of my outings to locate a swamp, I came across this beauty. In all my time playing survival, I had never been able to actually come across a mansion, without assistance from a map even. I searched through, got some useful loot, and even found a hidden room that had a spider spawner inside it, hidden behind a closed off wall. I'd killed another patrol that showed up outside of the mansion, so now I have Bad Omen once again. I think I'll go back sometime, I'd like to try and get one or more totems of undying.
