Rotigus causes repugnant plant life to spread about him in waves wherever he goes. Such is the strength of this power, that Rotigus feels no need to carry weapons and instead bears a Gnarlrod, covered in trophies and icons, which constantly rots and regenerates from a seed to bring forth ever-more foul diseases. He also manifests Nurgle's Deluge – a rotten, diseased storm that eternally hovers over his mountainous form and unleashes a vile downpour that spreads the blessing of Nurgle to every far corner of the battlefield. Rotigus is also worshiped by mortals in the far corners of the universe as a generous, life-giving deity of prosperity and fecundity. However the gifts he gives are foul in nature, and any who pray for his patronage soon see the error of their ways. During the Siege of Nebbus, the Great Unclean One was summoned by the Death Guard and the filth and madness he wrought ultimately claimed the world for Nurgle.
During his rampage across the Eastern Fringe, Rotigus infected many Maiden Worlds and thus incurred the wrath of the Harlequin Masque of the Frozen Stars. The Masque managed to perform a ritualistic dance that caused cleansing rains to purge the world of Rotigus' pestilence.
