Azyrite Halo

This circlet of Azyrite power lashes out at the enemies
of the faithful.
Azyrite Halo has a casting value of 5. If successfully cast, pick a friendly STORMCAST ETERNAL unit wholly within 12" of the caster
that is visible to them. Until your next hero
phase, each time you make an unmodified save
roll of 6 for that unit, the attacking unit suffers
1 mortal wound after all of its attacks have been resolved.
