That’s only works with the Devious status I think

No it works with any ​@@ChaoticDoodle

@@emirbergazden9723 oh ok, does this mean we have 2 obliteration routes now?

​@@ChaoticDoodlewell, the kill also works on pacifist/neutral routes but we can say that

Plus the fact he is still HOSTILE means sparing him is impossible.

Yeah, this version of UF sans seems like he’s unredeemable, and it’s implied he killed a human, presumably Frisk

Or at least attacked papyrus for not finishing them off.

Probably because before the 3.01 update which just came out where one of that changes is that it scales Sans' HP based on your LV, he had the same HP no matter your LV and by proxy ATK, meaning the fight took an annoyingly long time to beat on pacifist route

Mostly ya. After the half way point of section 3 the obliteration route is almost the same as the pacifist route.
