Its a modeling clay that you mold then bake it to harden it. Its great for making those odd figures you can not find or afford. A large brick of the stuff costs less then ten dollars. You can make an amazing ammount of minis out of a single brick.
Some time ago we had a mini making night. Everyone made some figs from sculpity and we baked them. I am no artist, but i am the only one with fig painting experiance so i painted them all. Had some help on the easier figs with base coating. The results are i think pretty fantastic for a bunch people with little artistic skill.
thats a Roper, 2 carrion crawlers with out legs... (legs are hard) and an Otyough. All unpainted, after baking.
Here is a purple wurm , with a painted mini for scale. the fig is a Reaper model.
Finaly i think this is the last of the unique weapons...

Arcanus, the spell blade. Can hold a single spell of 1st to 3rd level, as a ring of spell storing. Energy stored in the blade will dissipate harmlessly after a week.
