Blighting King
From Warhammer 40k - Lexicanum
The Blighting King is a slope-backed woe machine used by the forces of Chaos. Part of the group called the Hammerstone Kings, it was designed by Heritor Asphodel.[1]
The Blighting King has a rail-catapult on its back, used as a launching point for Blight-Balls and Hell Talons.[2] It is armed with a collar of rocket tubes[1] loaded with a mix of shrapnel, blister agent, asphyxiant, hyperbaric and incendiary warheads.[2]
