Refrain of Blazing Piety

The fervent intonations that the God-Emperor will
smite down his foes are believed so powerfully that
these sacred words can cause heretics to combust.
If this hymn is inspiring, select one enemy
unit that is within 12" of and visible to this
PRIEST model. That unit suffers D3 mortal
wounds (if that unit has the CHAOS keyword,
it instead suffers 3 mortal wounds).
