Goblin Slayer, Vol. 16 (manga)

To protect the nearby elven village, Goblin Slayer's party ventures into the dark interior of the jungle, where a goblin nest lies. There, they find an ominous tower rising above the canopy… Fighting their way up and out will put their skills to the test—and when they face a mighty goblin shaman wielding devious sleep-inducing magic, even the most honorable and pious member of the party may be driven to sacrilegious extremes!

Volume 16 of the Goblin Slayer manga series by Kumo Kagyu.
