Miner (Dungeons & Dragons)
The miner first appeared in the original Monster Manual II (1983).
The forest trapper (miner) appeared under the "lurker above" entry in second edition in the Monstrous Compendium Volume Two (1989), and reprinted under the "lurker" entry in the Monstrous Manual (1993).
The miner is a variation of the lurker. The miner waits on the floor of forests, waits until prey walks on top of it, and then attacks with two poisonous barbs.
