I don't understand what you meant with:
It can't be really an arrow type; I'm assuming you'd want to allow stepping *on* it.
I think that each object that is "
laid"
on tile and not tile itself (etc. wall, any door, pit, trapdoor) and changes directions from which you can enter tile and leave tile can be named Force Arrow - as it forces Beethro, monsters and mimics to enter tile from specific direction and then forces them to leave in specific directions (or not leave at all
)
Well, maybe I shouldn't at all use word "
glue"
- it should be force arrow looking like that (with arrow heads pointing towards center):

It's basically new type of force arrow - you can enter from any direction and leave in direction arrow points - as it points to the center of tile you can't leave that tile
.
I also thought about opposite arrow - which can't be entered but you (or monster, mimic) can leave in any direction - but it has only few uses.
