Here you can edit the guards of the room.
The game doesn't use the last digit of the tile number, only the given X coordinate. The X coordinate of the left side of the room is 144.
You should set the frame according to the following table:
2 False prince 63 Skeleton came to life with infinite hitpoints 77 Guard/Birdman 105 Flaming sword 112 Skeleton if comes to life 119 Skeleton if doesn't come to life 130 Head 170 Snake 175 Snake
If the guard is not a skeleton, you should set "Come to life (if skeleton)" to "Comes to life".
