Genocide Kill Counter?

[[TORCHWICK]]

So, I'm doing the Merciless Run (complete Neutral/Pacifist runs) and I'm in the ruins. I've been running about killing the random encounters. Does anyone know if there is a specific amount of NPCs I have to kill before leaving the ruins? Because I don't want it to really drag on

I think 15...... but you can tell by the message: "... but nobody came" then the music gets dark.

[He Who Is Vile]

You'd know when you all monster encounters are replaced by the "But nobody came" message and spooky spook music.

The actual kill count doesn't begin to show on save points until after you leave the ruins, although there are some situations where another message will override the kill count, so it's better to be safe and just murder everything until you get that one haunting message before moving on.

Ruins: 21 kills Toriel

Snowdin: 16 kills Papyrus

Waterfall: 18 kills Undyne the Undying

Hotland/Core: 40 kills Mettaton NEO

Final Corridor: 1 kill Sans

p.s: After killing enough monsters, your character starts keeping track of all the kills they've got in the pause menu~

So could I just farm enimies to get kills?

[(Edgy) Asriel Dreemurr]

It's 20 kills (not including the dummy or the first Froggit).

Also the kill counter you eventually do get doesn't include bosses. i e 1 left in Snowdin means you must kill 1 more monster before fighting Papyrus.

Ruins, 20 kills before Toriel, snowdin 16 kills before Papyrus (most sad kill in the game), waterfall 18 kills before Undyne the undying, 40 kills before Mettaton Neo, New home No kills (please don't rely on this xD)

I'm wondering if after I've met Toriel after wandering out of the hall if it switches since I've met Toriel before the exhausted kill count? ( EDIT: I got the spooky message nvm )
