Invigorating Aura

Add 1 to the roll for each friendly SBG HERO on
the battlefield. If successfully cast, pick 1 friendly
SBG SUMMONABLE unit wholly within 18" of
the caster. You can either heal up to 3 wounds
allocated to that unit or, if no wounds are
allocated to it, you can return a number of slain
models to that unit that have a combined
Wounds characteristic of 3 or less. The same
unit cannot benefit from this spell more than
once per turn.
