Crimson Eruption

True Fire Magic: Crimson Eruption (真炎魔法『唐紅噴火』) is a True Fire Magic spell.

Description
The user creates a natural mana array that encompasses a large area. The array emits a huge gout of flame that engulfs everything within the magic circle.

Due to its size, the array takes time to set up but allows the user to attack a target without knowing their precise location.
