Obstacle, Well of Darkness
I - Rules
(see WOD, p. 4)
A small figure (hero or monster) must spend 2 movement points instead of 1 to move onto a mud space, or from one mud space to another. It costs only 1 movement point to move from a mud space to a non-mud space. If a small figure only has 1 movement point, then it cannot move onto a mud space.
Large figures are affected by mud, but only if they make a move that results in the entire figure occupying mud spaces.
If a hero or monster is aware of mud, it may jump across the mud as though it were a pit.
Line of Sight
Mud does not block line of sight.
