How do I 1 hit kill papyrus

[PINEOINE]

I am doing a genoside run but i dont know how to 1 hit kill papyrus help.

In the run, it's insta-kill. It should immediately say "Papyrus is sparing you." If you don't have the option to only fight (Act doesn't work, Items don't progress anything, Sparing shouldn't be used on a Geno route), you've done something wrong.

You probably didn't do it right.

1]In Ruins, you must kill EVERYTHING. It will be RIDICULOUSLY OBVIOUS when you killed all the random encounter. Not it "takes forever to find a fight" but actually RIDICULOUSLY OBVIOUS. Remember, no letting Toriel survive either.

2]after doing that for Ruins, do the same thing for Snowdin region ebfore entering Snowdin town. you MUST kill all the dogs and also snowdrake or else the run is aborted down into neutral.
And, by the way, "that comedian" is Snowdrake, not Sans.
