Racked up almost 800k pts in labyrinth and saw not one arc brace drop for me or my party. However, I've come across a few in town who weren't even plat tier(24k pts) that has looted a bracelet.
It does not depend on how strong your gears are, it's all in the rng. Idk where and how you even got the idea that higher stats means better chances of looting things lol. So absurd.
