Blaze of Glory

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