Magic Cannon Flower

Plant Magic: Magic Cannon Flower (植物魔法『魔砲の花』) is a Plant Magic spell.

Description
With an open grimoire, the user creates a large flower and, from an opening of the petals, launches a powerful beam of concentrated mana.

The spell could also be grown around corners, allowing the user to fire from cover. When used with an even greater Mana, the user is capable of burning and making a Dark Disciple faint.
