But then we ended the session before she could try, and now that I've had time to think about it, I'm wondering: based on the text of the spell, could she actually speak to any of them if they started questioning her? Seems like all it allows the spellcaster to do is understand what they're hearing, not respond.
I really want my players to be able to pull this off, but unfortunately none of them thought it was a good idea to take Orcish as a bonus language.
The team's Cleric is a high enough level to have access to tongues and the Warlock has telepathy, but neither of those options will allow them to talk to a pack of Orc guards without giving themselves away as foreigners to the rest of the group.
How do I get them through this without doing some serious DM hand-waving?
Is there a spell, magic item, or something else that allows a character to speak a language she doesn't know (without giving herself away)?
