Ethereal Marauder

thingiverse

DM: You arrive at a dead end, with bones and something shiny scattered on the floor. Player: I take a closer look at the bones. DM: As you examine them, the air seems to ripple and a gaping mouth with razor-sharp teeth materializes in front of you. Three jagged mandibles now hang menacingly, right at head level. Roll for Perception to see if you catch on. Rest of the party: You're not getting away from us that easily!
