Four amethyst-colored hexagon crystals continuously hovered around Xia Fei's body; their speeds were neither fast nor slow as if they were deliberately protecting Xia Fei.
The crystals were only palm-sized, and the faint amethyst color glowed mysteriously with each edge being as sharp as a honed blade. Anyone who touched it would most definitely be severely injured by the sharp edge.
This was Xiao Yu's special ability, Amethyst Guard!
Protection Special Abilities were considered marvelous out of all the possible Special Abilities. Not only could these crystals automatically defend against an enemy's assault, but they could also unleash it to attack the other party. More importantly, Xiao Yu would be able to assign some amethyst crystals to her teammates to assist them.
If a team had a high ranking Protection Ability User, then the team's combat prowess would undoubtedly increase significantly.
