Warpstone Weapons
(Rule)Description: The following Skaven weapons contain enough warpstone to count as magical, and so can damage creatures invulnerable to non-magical weapons:
Assassins' and Gutter Runners' poisoned weapons. plague censers' gas and hits, Warlock Engineers' warp-blades. warplock pistols. poisoned wind globes, Jezzails, Ratling Guns, warpfire Throwers and Warp-lightning Cannons.
