The Planetarium Logbook is a hidden item that can be collected in Risk of Rain 2: Survivors of the Void. This item is obtainable when you come across the Diviner of Deep Voidling boss.
As a newly released game, a big percentage of people will have difficulties collecting these hidden collectible items. Not to worry! This guide will show you how to collect the Planetarium Logbook in Risk of Rain 2: Survivors of the Void.
Planetarium Logbook Location – Survivors of the Void
Location & How to Get
The Planetarium Logbook is obtainable once you reach the Hidden Realm: The Planetarium (Cell V). Once you reach this location, you will need to glide down until you reach a big-looking arena. Here a giant boss will spawn named Diviner of Deep.
To get the book you will want to ignore the boss and jump into the circled hole in the middle of the battleground. Before jumping, I suggest you zoom into the middle where you will find the Planetarium Logbook floating in the middle of space.
When the book has been located, make sure to jump down and aim towards it. As you get closer to the book, simply try to land over the book and it will be automatically collected. You will fall just a bit further down into space, and you will respawn on the battlefield to fight the Diviner of the Deep.
