Jet of red light
The incantation is most likely derived from the English word "vermillion", a shade of red. The modifier "duo" applied to the spell means "two", referring to its status as the second variation of the charm.
Behind the scenes
- This is a more powerful version of Vermillious and a lesser variation of Vermillious Tria.
- It may, given the similar sound in incantation, be related to Verdillious, a spell to create green sparks.
