The lizardmen that have had a lot of contact with amazones or 'civilized mankind' resent being hunted and actively seek to get even. And what better way than to make a special pole where any captured enemies can be slowly killed?
This was an easy one to do
The skulls is a candle holder, and I just had to paint the pole and insert it into the candle holder. I used 3 half corks to hold the pole, and then poured spartle over them. Some decoration gravel glued on top, and then just a varnish job.
