Nurikabe
About
A nurikabe appears on a night road as a wall that was not there a moment before. Walking around it only lengthens the wall, climbing it finds no top and turning back leads to the same place.

Special Attack
Closing Wall: creatures in a 20 ft line make a Quick save. Those that fail take 3d6 bludgeoning damage and are pushed together against the nearest solid surface. Road Without End: one creature within 60 ft makes a Mind save or loses its movement for 1 round while walking a road that goes nowhere.
Special Defense
Strike Low: an attack aimed at the ground where the wall meets the road ignores DR and deals double damage. A traveler who sits down, shares food and waits until first light may pass without fighting.
