Blaze of Glory

If a friendly Stormcast Eternals model is slain
within 1" of an enemy unit, before
removing that unit from play, pick one enemy
unit within 1" of that model and roll a number
of dice equal to the wounds characteristic of
that slain model. Add one to the number of dice
rolled if that model has the Thunderstrike
keyword. For each 6+, the target unit suffers 1
mortal wound at the end of that phase.
