User:JRMHD91/Blog:The "Playful Killer" Run

In this Genocide run, make sure to play along with all monsters you encounter, or, Playful Killer Mode. Play all battles as if you were Pacifist, check on enemies to see lowered stats, and experiment on enemies you will fight multiple times. (Ice Cap for example). Certain triggers like the spider bake sale or interacting with Vegetoid in field is up to you. This is my current run.

Dummy - Check, Fight.

1st Froggit - Fight, make sure to kill on 1st attack.

Froggit (in ruins) - Compliment, Fight.

Whimsum - Terrorize, Fight.

Moldsmal w/ Migosp - Imitate, Flirt, Fight, Talk, Fight.

Vegetoid - Dinner, Fight (also do Fight, Fight, Devour)

Loox - Don't pick on, Fight (also Pick on, Fight)

Here's where it may matter how you decide to defeat Toriel, since in this theoretical mode you want to exhaust all of the battle and not harm any boss monsters

Toriel* - Spared entire Fight sequence, Spared 7-8 times in game dialouge

I bet you have an idea how this play is going to go,  the idea is we're triggering flags in game, so maybe that's worth exploring if you play the game differently, although some things will conflict with this play style later on due to the strictness of following a Genocide route.

Try it yourself or wait for part 2 of my test run!
