Prison Kill Buckshot

Fire Magic: Prison Kill Buckshot (炎魔法『獄殺散弾魔球』) is a Fire Magic spell.

Description
With an open grimoire, the user generates multiple fireballs at once and can throw those fireballs as a barrage of attacks on a wide area.

Upon contact, the fireballs generate explosions and deliver extensive damage to the target. Additionally, the fire from this spell will not vanish or wane, which could be used as an extension for other spells.
