I've been wanting to get a ruined tower completed for some time for use with Frostgrave, Advanced Song of Blades and Heroes, Warrior Heroes Legends or any other miniature games. Where I work we have a lot of cardboard cores that come in with some of our raw materials as spacers. Perfect for a tower, or at least the start of one.
I cut is apart and stacked on piece on top of the other. I also found some 1/4" thick pink insulation board and cut a circular base that I then scribed a stone pattern on it. On the outside I cut a few pieces of thin cardboard to simulate a stone pattern. Glue to an old CD, prime with grey paint and I had a good start.
The fun part of a ruined tower on a table is the elevation it can provide for missile armed troops and fire-ball throwing mages. So I added to levels of partially ruined wood floors. The first floor started with a piece of cardboard cut to the inner diameter. I then glued pieces of wooden stir sticks left over from a special event where I work. Then painted with a wash of thinned down brown paint. I then dry brushed with lighter browns to give a weathered look.
The second wood floor would be much smaller. I glued a square balsa wood piece for the second floor base. Then I superglued more wood stir sticks that were painted the same way. Note the white in the back of the first floor is still wet white glue. As this will be a tower used for Frostgrave I still need to add snow and ice to some of the flat surfaces. I also need to put snow along the back where the glue is still wet. I'll also make some rubble to represent the part of the tower that has crumbled.
Thanks for looking!
I had this miniature for a while. It was partially painted. I needed another fire-themed wizard to go with the first one. This is a Reaper Warlords metal miniature - Ian, Ivy Crown Mage. 
Worked on my ruined tower small bits at a time. The snow is a mix of PVA glue, white paint, baking soda and a small amount of glitter. The glitter didn't come through much to give the effect of ice crystals. I'll try another layer of just glitter and PVA glue to see if it reflects the light better.
I've got one ladder built and painted. I still need to get a second ladder built and painted. I'm also working on a rubble pile to represent the section of the ruined tower that is on the ground.
