Know Vulnerabilities

A Monster Trait.
From the Book of Engoku:

Description

The creature has a vast knowledge of the arcane, and knows exactly what weaknesses their opponents have. This includes all Vulnerabilities, even those that are chosen by the player (such as with Extra-Planar Entity’s). The player may ask a nearby Reeve to list any Vulnerabilities their quarry has.

Currently, Pipek is the only monster bearing this trait.
