So I'm trying to find the range on activating an item with a command word, and I can't seem to find any mention of a range. I'm taking a campfire bead with my barbarian Ifrit, but I was thinking in addition to a fires domestic uses, I could use it as a trap. Place it beforehand, and ready an action for when an enemy goes through that square, speak the command word, and have it ignite, burning the unfortunate soul that walks through.
Does anyone know where the range of a spoken command word is listed? I couldn't find it in the Core rulebook?
If it's not listed, I was thinking 30ft in combat, or 90 feet if it's quiet.
