Any model or unit responsible for the death of Queen Khalida (see the Tomb Kings' Curse) is affected by her curse on the dice roll of 4+. If affected, then roll a D6 for each model/unit, and on the dice roll of a 6, the model loses a wound that cannot be saved in any way (including Ward saves) nor Regenerated. Roll again at the start of each of your opponent's turns for the rest of the game, and they take a further wound on a roll of 6.
