Arrows of Judgment

Light Magic: Arrows of Judgment (光魔法『審判の矢』) is a Light Magic spell.

Description
With an open grimoire, the user releases their magic power in a sphere around themselves. As the sphere expands, it flattens out and is shaped into countless blades of light. Once complete, the blades rain down on and automatically target those below.

The user could also take hold of a blade and use it for a close-range attack.
