Chest drop rate

[kev1n]

What is the drop rate of the weapon you need in chest? I dont really ge it . I ve lost  80 keys (something like that ) to earn hujikar dagger, now im  trying to earn imperator dagger. I ve lose 16-18 keys ( 1 chest = 1 key). is it some kind of a joke or what?

Thats RNG. You can either ask if someone wants to trade the imperator weapon for the one you need.

Huijikar....yeah either farm or use a brilliant key.

There alway a marketplace to buy item if you don't want to farm.
