Elder Dragon Jewel use?

[kibukimura]

I was wondering about this Item

Elder Dragon Jewel 
---[Offering for Accesory That require level 1-60]
[Available at any accesories level]
[Grains an Equal Amount of XP at All Levels]


I think this looks like a very cool item
but for example accesories of BT [that are lvl 50 and 55 i think]
you cant use this item on them [i maybe i dont know how to use it]

maybe the last description is to much powerful
but it could be cool if at least if we cant use it, then get an option of salvage it

these were used back in the old days to upgrade accessories, similarly you had the equivalents for weapons (back in the dday upgradinhg weapons was like upgrading accessories you could use the dragon jewels as offerings or other weapons etc).

 

Current Legendary jewels / elements are just an updated version of the dragon jewels.

it would be nice if the devs could antique this to make these exchangeable for legendary elements/jewels as now it has no useage and we can still get it from transmutation.
