Many people has killed Elite Rahabkor more than 1,000 times, and yet I believe that there are 2-3x of that aura in the game. (and those were looted from locks, not Elite Rahabkor)
Increase the drop chance by a little bit, not too much that some lucky players could actually loot that.
cause rn the odds of looting one from rahabkor are the same as winning the lottery
