Seed Pods
From WikiRaider
The Seed Pods of the Dreaming Blossoms are a vital ingredient to the Antidote for the pollen that induce fear and visions in everyone who enters the Wicked Vale in the Baba Yaga: The Temple of the Witch DLC of Rise of the Tomb Raider.
Lara has to collect some of these pods to create the antidote so she can enter the vale without being terrorized and disorientated by hallucinations..
