That would hint at the possibility that there are no plans for us to get that map, or that we get different rewards?
Overal, I'd suggest changing the bracelet, so it could
-be upgraded to get some defensive stats (would improve the bracelet as well as make people suffering OCD happy, since those will go nuts from seeing lvl 1/50 without being able to ever make that 50/50!)
and/or
-stack with character passives
and/or
-be worn in the personal equipment slot
Ideally, all three, in which case the bonus stats from leveling the item wouldn't even need to be high. Just about 2 points of DEF per level would be more than enough.
