Vermillion Scourge

Created for the "Red Mage" Sorcerer archetype by ItzNate. Based on the Red Mage Level 3 Limit Break "Vermillion Scourge"  from Final Fantasy XIV. Also known as "Verflashbang" and "The thing that wiped the whole alliance in Tower at Paradigm's Breach."

When dealing or taking damage of ten HP or more, you gain one Limit Charge. At six Limit Charges, you can expend all of them to begin casting Vermillion Scourge. 

Begin casting for one round, and on your next turn target a space within 60ft. A 20ft. circle of blinding Red Magic erupts from the ground in the space you targeted. All Creatures in the circle must succeed on a Dexterity saving throw or become blinded for 1 min. In addition, the creatures take 25d8 Force damage, halved on a success of the DEX Save. This damage can not be resisted.

Damage dealt by this ability does not build Limit Charges. You can only cast this spell once per combat encounter. This spell does not affect you if you are in the spell's radius. Limit Charges built are expended when combat ends. For the first round while casting, this is considered a Concentration spell.

Though Vermillion Scourge is a 9th level spell, casting it does not consume a 9th Level Spell Slot.
