Each time an enemy unit shoots or fights and the bearer was selected as the target of any of that unit's attacks, after that unti has finished making its attacks:
Roll one D6 for each wound the bearer lost as a result of those attacks: for each 4+ the attacking unit suffers 1 mortal wound.
If the bearer was destroyed by those attacks, before removing it from play, roll one D6: on a 4+, the attacking unit suffers D3 wounds.
