Blaze of Glory

If a friendly Stormcast Eternals model is slain
within 1" of an enemy unit, before removing
that model from play, pick 1 enemy unit within
1" 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.
