How to get those Unique weapons!?

Having read the Japanese wiki I found out how to get those super OP Unique Weapons.
There are these Mystery Boxes you get starting from level 42+ by collecting Rutile Quartzes from around the Runnersville dungeons, exchange 30 of them for a Mystery Box

The Mystery box has 20 different items it can drop.
Highest drop rate is of [Common]Jewelry Box that you can sell to NPC for a mere 10k..
Then there are [Valuable]Jewelry Box (30k), [Beautiful]Jewelry Box (50k) and [Precious]Jewelry Box (100k)
Other drops include 12 Different Rare Ores
+ 4 Very Low chance drop Unique Weapons

Any link of those weapoans?O_o
