Bagpuss said:Have the terrain like a rabbit warren, why would goblins make all the tunnels tall enough for humans to walk upright. Have the main natural caves large enough for the PC's but have it intersected with looks of smaller tunnels (which the goblins dug themselves) that the goblins, can run through fine, but the PC's have to duck thus are squeezing. That will discourage them following the goblins when they hit and run.
Rechan said:That does give me one thought.
If your goblins are particularly ruthless, send in the women. Just like, "Go, run at them or we will chop off your feet!"
Stampede of 20 commoner goblins with babies in their arms. One of them is a female warrior with a knife in her hand. (Or several of the males are disguised as females; can the PCs tell a boy gobbo from a girl?)
Bagpuss said:You know they could do both, fire a single shot then use the move action to scatter. That would be really mean. It's only a 10ft burst, so while it could get some you can't see, with their 30ft move they should be able to make it impossible to get more than a few.
