Elpathion's Transcendental Lighthouse Skill - Crystal Mirror Room (엘파시온 등대 초월기 크리스탈미러 룸, Elpasion Deungdae Chowolgi Keuliseutalmileo Lum) is a Lighthouse Flow Control technique of Elpathion, a Vice Corps Commander of the 4th Army Corp of the Zahard's Army. He is an advanced Light Bearer High Ranker. He used this technique against Evankhell, trying to slow her down from moving so that Lo Po Bia Lefav, a High Ranker sniper-type Spear Bearer can aim for her head. However, Evankhell managed to break free very easily and the effect didn't even last for 10 seconds.[1]
