Please help me understand what is the use of this elixir? What does it really do?

ring/pendant/belt category is consider for all class as an equipment.
armor/helmet/weapon category is class based but what is there worth looting by using this elixir?
this elixir also does not stack with anything else either.

all that left is Crafting items and Chests category.

Crafting item apparently is not luck base it drop random and whenever it feel like dropping lol.

Chest category I believe is for all classes also but it require LUCK ELIXIR and All class can open any chest and egg if the owner chooses to.

So this leave me still wondering WHAT EXACTLY DOES THE 25% CLASS LOOT ELIXIR USE FOR? What exactly is there to loot to benefit your own class instead of looting the other class item.

Suggestion if the gaming mechanism allow it. Could it be possible to use it to upgrade with lock allowing the lock to be open and give out class specific?

Also to allow Jewel to be drop class specific? only apply to 3 type of jewel (FURY/FINESSE/MIND)

any thoughts?
