The Divine Father Descends

When a Hero falls in battle:
The caster becomes enraged, while pure divine energy descended from the sky covers the caster in bright light, that makes all type of creatures in the area hard to keep their eyes open.
And then, in an instant: An enormous figure of an elderly man (325 feet tall) emerges from the caster like an explosion of light, damaging all type of creatures in the area for (?) Divine damage.
