I made some more lava hexes.
Here they are alongside some standard Hexon II tiles.
I think I'll make some intermediate tiles to blend in the 'join', so to speak.
The 'join' is a bit abrupt.
The archers seem unwilling to advance, depending on their arrows to dominate the lava field.
These are GW Empire plastic archers painted in a variety of house colours and form part of my humanoid fantasy army. The painting style is semi-old school, block painting finished with a coat of nut brown ink and matt varnish. The bases are magnetised.
