Step-by-Step Walkthrough

1

Meet Calip

Calip's observatory is on Washa's Bluff. He explains the Blood Moon's Gloom-energy origin and gives Link three Atmospheric Collection Vials to be filled at specific locations.

2

Sample 1 — Hyrule Field at Midnight

Be in the center of Hyrule Field when a Blood Moon triggers. The vial absorbs the reddish atmospheric energy.

3

Sample 2 — Depths Below Hyrule Castle

Descend into the Depths below Hyrule Castle during a Blood Moon. The underground energy here is stronger and tinged with ancient magic.

4

Sample 3 — Great Sky Island

Be on the Great Sky Island during a Blood Moon for the third sample. The altitude gives a pure reading of the Moon's Gloom frequency. Calip's analysis reveals the cycle can be predicted 20 minutes in advance.
