[pnpgm] Rock vs flier

[Alex Koponen]

Z'leyra wonders "Could a trap be set such that the fliers, presumably 
flying out of the cave entrance run into a net cabled to an anchor below 
the entrance so the flier runs into the net then swung around an arc and 
slammed into the mountain wall? Perhaps with spare nets ready to place 
for the next flier? Alternatively a boulder placed there in their flight 
path but somehow concealed so they don't notice it, perhaps the boulder 
hung from a cable? I doubt that running into a boulder would do much 
good for a flier."
