try getting insane by potion then gets defeated.
thats how you get most of the game overs
There are also a ragroaches, Rat King, Vicoria, corrupted lizards (or/and Roushk in the lake of corruption), Alpha Werewolf, red orcs, swamp werewolfes (and maybe that strange tentacle tree in Misty Abyss?), Hornet matriarch (only while doing the country road quest; you should be a female or have feminine juice in inventory). Also i remember something about Ste in glory hole, but i never tried this one.
Lol, I never realised before that there are so many of them :D
Weird, ragroach let me go afterwards. Also argh, I even GOT the corrupted lizard and alpha bad ends, and yet totally forgot about them before I came here to respond. Admittedly forgot about the swamp wolves. Red orcs though? Is that a specific type? I had tried several of them. I went into every battle with only 5 sanity, so it shouldn't have taken multiple tries.
Do some ends take the battle ending in a way besides submitting when they're horny?
I do remember having the red orc game over scene by fighting one on the wasteland(near orc tribes). those red orc with their dicks literally hanging around. I fought them with a very low sanity, and I think it's a very low chance, but one of their move(and I think it can only happen if they're turned on already) is the red orc grabbing your head and yeah. but no game over if you just submit to them tho, they really have to do that specific move on you on a battle.
