Labyrinth

At the best of times the underhive is a maze, though
here it is especially tangled, and fighters might find
themselves easily separated from their allies and alone.
When a fighter that is without line of sight to
another fighter (either friend or foe) activates,
they must make an Intelligence check.
Fighters who fail this check become lost and are
placed anywhere on the battlefield within 12" of
their current position by their opponent. They
may not be placed in impassable terrain
