In the Dark Forest, I've run up against a number of cliff plateaus. I've also noticed that a number of these plateaus have monsters that can actually target me and throw ranged stuff (big spiders for example).

Is there a way for me to get up that cliff wall? Near the Imp castle I tried throwing my teleporter stone over a layer of brush but it wouldn't let me. I like nice clean and cleared maps...any help is appreciated (spoilers ok).
