Sake

A Monster Vulnerability.
From the Book of Engoku:

Description

This being has a taste for Sake, and as long as there’s a supply available, will drink until it passes out. Must chant ‘Drinking’ for a 300 count, and then affected as Subdued for a 600 count. If the creature has many heads, only one need drink, but the effects will be felt by all.

Currently, Orochi is the only monster with this Vulnerability. This is due to legends telling of great warriors slaying the beast after intoxicating it with sake.
