One of our party went out in a city to deliver a message, and when "they" returned it was a doppelganger. It ended up being killed fairly quickly (yes, at the hands of the party). Now we are wondering about our missing companion and if they are alive or dead. How can we determine if our missing party member is alive or dead?
Our party is level 4. Currently most of the suggestions are too high level, and will force us to hire a spell caster. Is there a low level method?
