This 51-piece kit can be used to build either a Warp Lightning Cannon or a Plagueclaw Catapult. It includes a large chunk of warpstone, several wheels of varying size and stability, rickety wooden beams for the infrastructure, a large warp lightning cannon barrel, a pile of toxic sludge and two sets of crew to represent either Clan Skryre or Clan Pestilens.

This set contains one plastic Skaven Warp Lightning Cannon/ Plagueclaw Catapult and one 50x100mm Monster Base.
