yea, thats right. I mention in the description that that it is one of two original mechanics i did not implement (the other being scroll of push letting you kill monsters by pushing them into traps/hell vents/etc)
reason i didn’t implement is because i would need a better UI just to allow targeting monsters in and out of the room and it could be a little confusing(monsters don’t have unique names, rooms don’t have unique labels, etc)
i can try and implement it when i have some time, but that wont be for a few weeks as I’m currently on vacation ;) ill make a dev post if/when i add it to the game. No promises though, i have an idea for a proper game in this style that i will most likely be working on instead of continuing doing anything with DNGNCRWL.
