Luxurious Necklace of Destruction Lifetime did not renew
I purchased, equipped, and did many PVPs to level up this item, Luxurious Necklace of Destruction III, Luxurious Necklace of Destruction from level I to level III. But the lifetime on the necklace did not renew each time it levels up.
Each of necklaces have a different lifetime, the one you have equipped now is 3 days. It does "reset" their life-time each time you upgrade it to next level.
You can check how different quality necklace life-time differs here in library:
It is degraded by one tier each time the lifetime of necklace runs out, but point still stays that the higher quality the necklace the smaller is the lifetime of it.
