Multi-Planar Existence

A Monster Trait.
From the Book of Engoku:

Description

Such Monsters may attack players using Blend, Camouflage, Circle of Protection, Commune, Passplant[sic], Sanctuary, Sneak and Teleport. Players so attacked may defend themselves normally, but the Monster must declare its ability before engaging in combat. (It’s not cool to jump people who think they are safe without warning them.) In scenarios that use the ‘Talk to Kami via Speak with Dead” optional rule, this trait also imparts the ability to speak with any Kami in the area. This trait affords no additional protection or abilities other than those listed.
