Just for jollies I thought I'd post my Pit fight Arena
I made 2 just alike a couple of years ago.
I made the hexes oversized since the origional ones from GW couldn't completely hold 25mm bases without spilling over.
This is one of them with some of my warbands cheering on their sacrifice...I mean champion.
If you'll note, the black dots on the back of the skaven let me know which henchman group is which.
