As for the terrain pieces, they're all very Icy themed and I wanted to create pieces that could be allocated different attributes (although I did end up making a tonne of blocking, impassible, hard cover terrain pieces). The majority of the terrain pieces I made were ice pillar formations. I did this for a few reasons. The first, They look really cool. Second, I needed to make Raspy some summon-able pillars she could use IG, and well I figured since I was making a couple, why not make more?
I spent one night watching The Fresh Prince of Bel-Air reruns and whittling polystyrene into crystalline shapes. I kind of lost track of how many I was making and that resulted in making quite a few terrain pieces of the same nature. I eventually varied the height and made some Ht1 blockades. They got painted up and I finished them with crackle paint cracked ice base and a decent bit of snow
I then went and made a few pieces that could be used for either severe terrain or hazardous terrain. Keeping in theme I went for some heavy fissures in the Ice. I realize I don't have any good pictures of them, but here's one in front of Von Schill
Then I made a couple of Ice gamin igloo/cave things to add some more diversity.
Give me a shout if you'd like a bit more detail on how any of the pieces were made!
