Grade 4 Artisanal Skybuilders' Silex

Similar─though rather less artisanal─sacks of silex are sold to the participants in Ul'dah's Coliseum. A well-aimed handful of the stuff can temporarily blind the opponent, though it is only a matter of time until these customers realize that the same is true of the sand that lines the arena floor, which is available for free.
