Arun Spark

Aruṇ Spark (アルンスパーク, Arun Supāku; for "Dawn") is a supplemental technique.

Overview
Frost holds his hand out in front of an opponent causing a bright flash to emerge. It lasts for only a second but serves to completely blind anyone looking at it at the time. Those who witnessed the flash find themselves unable to perceive Frost for a short time, instead their vision becomes clouded and allows them only to see a hazy mist around themselves allowing Frost to attack freely without fear of repercussion. This effect lasts a few seconds at most, serving largely as a means of creating a gap for Frost to unleash a powerful technique or to create an opening with which to escape.
