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 slain 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.
