Eye of Recovery is a skill used by Alice in Chapter 3. After Luka requests her to use Word of Dispel, Alice revitalizes his health completely.
This skill is useful when there are long-drawn out battles against monsters, where defensive countermeasures are needed. It is also useful against angels, as Alice cannot harm them.
It is first seen in the battle against Kraken, in chapter 1, where Alice restores Luka's sleeping status effect.
