So I'm trying to figure out how Shadowcloy Flasks work. So it says that a direct hit causes the target to treat light around them as one stage darker. Does this mean that it blocks their vision, making them perceive darkness that isn't really there, and only working on them? Or does it make a cloud of darkness? The reason I ask is because I'm running a game for a Fetchling that wants to use it as a sort of smoke grenade of darkness. He wants to know whether him throwing it at his feet would obscure him in darkness or whether he'd look like a twat. The wording of the item seems open to interpretation.
Well that happened. Thanks.
