The Champion and any unit he is with are surrounded by a cloud of nauseous gas. Any enemy fighting them suffers -1 WS in hand-to-hand combat. Any unit with the Champion is unaffected by the smell.

After making normal attacks in hand-to-hand combat, roll D6 for each enemy model in base contact. On a roll of 6 they contract Nurgle's Rot and suffer a single wound. Even magic armour may not save.

A cloud of flies surrounds the Nurgle Champion. All enemy models in base contact suffer -1 to hit, whether they are attacking the Chaos Champion or another target.
