Stone Eyes

Stone Eye (石眼 Ishigan) is an Eye Magic utilized by Thunder God Tribe member, Evergreen.

Description
It's a special eye Magic which allows the user to turn anyone who looks directly into her eyes into stone. This ability is very similar to the Greek Mythological monster, Medusa. Over time, those who have been turned to stone will turn to dust, and she is supposedly able to turn them to dust upon her own command. This Magic only works on humans. However, if the victim has a prosthetic eye such as Erza Scarlet, then the effect of the Magic is halved, allowing the target to break free from the stone. The Magic also doesn't work on people who wear glasses.
