Before the launch of Talisman 3rd Edition, Games Workshop made a series of boxed sets of plastic miniatures for use with Warhammer. These contained enough minis for a "unit" of sorts to bulk out your forces and would also give you a bit of practice with painting.

As the cost of moulds for these miniatures are rather costly, Games Workshop reused these figures in other games, like Talisman 3rd Edition and Warhammer Quest. So if you come across one of these boxed sets, you know you have the means to replace a couple of your Talisman figures!
