Embodying the decay and resilience of diseases, your stagnant soul have become the undying Champion of Nurgle, turning your body into a living vessel of pestilence and disease. Your body becomes host and ruler to a myriad of virulent plagues and contagions, emanating a miasma of filth and decay. Merely being near you weakens and sickens your foes, draining their vitality and sapping their strength. Your own constitution becomes nearly impervious to harm, allowing you to endure wounds and injuries that would cripple even the mightiest warriors.

The Rotting Throne of Entropy
You have inherited the unchanging stagnation and sweet rot of pestilence, inheriting Nurgle's mantle as the Chaos God of Decay. With your ascension, you gain access to a new warp realm known as the Rotting Garden, where the cycle of life and death perpetually thrives. As the Rotting Garden feeds on the suffering and despair of the universe, your own durability and regenerative abilities reach unprecedented heights. You become an avatar of pestilence, spreading world ending plagues and diseases with a mere touch. The Rotting Garden teems with grotesque creatures and daemons of Nurgle, bolstering your forces and infecting reality with decay.
