Vault Hunter's Relic

root@eridian-db:~$ cat description.txt

A unique Eridian relic that improves loot quality by reducing the weighting of common drops, which indirectly raises the odds of finding higher-rarity items. The effect is real, but modest, and its value depends heavily on whether you are willing to give up a stronger combat relic.

root@hyperion-db:~$ cat notes.txt

It was awarded through Premiere Club bonuses and is also included with the Mechromancer Pack.

Its effect stacks in co-op when multiple players equip one, and its loot modifier is fixed rather than randomly rolled. It cannot normally be traded or dropped.

If you swap it for a relic on the ground while your inventory is full, it can vanish. If that happens, you can make a new character to obtain another copy and move it through Claptrap's Secret Stash.
