Monster maneuvering next to walls
Monsters won't walk around one another while next to a wall (sometimes)
If a monster is standing diagonally down and to the left of a wall and the PC is above them, they will not move around any monsters that are standing between them and the PC. They do not do this while in any other configuration. This can lead to situations that look like this:
Code:
#########
#...../.#
#.<...#.#
#.....#.#
#######.#####+#######
#./..........@+
###.....!....r#
#..........r#
#..........r#
#...........#
This allows players to survive more easily in big rooms/wilderness encounters/against summoners and to even the odds a bit when fighting more than one strong enemy at a time.
