Project P.I.T.T. How Do I Get the UV Lamp?
How Do I Get the UV Lamp?: Official notes document collection/activation behavior, not the complete current acquisition chain.
Official notes document collection/activation behavior, not the complete current acquisition chain. An older mining reward claim is not a replay.
Answer scope
Update 1.0.5 changed collection behavior and states that default T activation is still required. The patch note does not document every final-release interaction.
One first-hand older guide describes fuse, weight, pipe, mining, UV and keycard steps. Its IGTAP units conflict internally and the Cauldron changed later; do not present a verified full route.
