First " dark " weapon idea

[-VegettoBlue-]

As in the MMOrpg "ViperMU, Order and Chaos, Mmo Civilization, etc." there is a special weapon class, being stronger when upada, this type of weapon starts as common and increases the rarity according to the intens that you A order to be able to "craft" her, is a challenge for her in the last rarity and stronger level of all.
My idea would be to do this even if adding levels to this weapon according to rarity.
EX:
-COMUM gun lvl 1-10

-RARA weapon lvl 11-20

-LENDING weapon lvl 20-40

-MISTICAL weapon lvl 41-45

-DARK WEAPON LVL 45-46

BEING TO UPAR FOR MYSTICS AND DARK WOULD BE ABSURDALLY DIFFICULT.
