True Lab

Major spoiler warning. The True Lab is a late area tied to the peaceful path and Alphys’s secrets. Enter only when the story points you there — usually after a Neutral clear and the befriending steps for True Pacifist.

What it is (still light)

A science wing beneath the lab: power puzzles, amalgamates, entry logs, and answers that reframe earlier Hotland oddities. Bring healing, read every log, and keep moving when the lights fail.
