Boon of Mutation

Pick an enemy unit within 18" of the caster and
visible to them. That unit suffers D3 mortal
wounds. For each enemy model slain by these
mortal wounds, you can add 1 new
TZAANGOR model to a single friendly
TZAANGORS unit. Each new TZAANGOR
model must be set up wholly within 12" of the
caster and within 1" of the unit they are being
added to.
