Deathmaster Snikch
Deathmaster Snikch, Chief Assassin of Clan Eshin, is a skaven special character for Warhammer Fantasy. Introduced in 4th edition, Snikch triple-wields the deadly Weeping Blades of skavendom - enchanted weapons infused with toxin and warpstone during their very forging - and wears the invisibility-granting Cloak of Shadows.
One of his greatest achievements, by far, is that he was the one to slay Thorgrim Grudgebearer, last High King of the Dwarves.
