Q: When Cavern Moss is attached to an Item asset, does it attack you? This is a question for both normal attacks during the enemy phase and for attacks of opportunity. A: For Cavern Moss, while it is attached to an asset, it is not considered engaged with you, and it does not make attacks of opportunity nor attacks during the enemy phase. You cannot evade it if it’s attached. (Rules Forum Answer, May 2024)

Q: I have questions about enemy card Cavern Moss. 1) When attached to a card, can it detach as a result of passing skill test by an investigator at its location? Or does this ability no longer work once attached? 2) When Cavern Moss is attached to item card, can I deal damage using a skill like the one on a Beat Cop? Or can I parley with attached Cavern Moss or use other abilities that are normally used on regular enemies? A: 1) Yes, Cavern Moss’s Forced ability still triggers while it’s attached to an Item asset. If there is another Item asset under your control besides the one it’s attached to, it will attach to that other asset. 2) Yes, you can target Cavern Moss with abilities that target enemies at your location. (Note that while attached, it is not considered engaged with you unless you’re attacking it; abilities that don’t require the enemy to be engaged can still target it.) (Ruling, April 2025)
