Glimmer is a purification spell from Dragon Quest: The Adventure of Dai.

Dragon Quest: The Adventure of Dai[edit]

Glimmer purifies an area, freeing the monsters inside it from the dark influence emanating from dark lords such as Hadlar. In order to cast it, the user must draw a circumscribed five-point star in order to establish the area of effect of the spell. Avan and Popp are able to cast this spell.
