What is percentage chance of getting Prison Keys from Unrealized Dream?

Question

I collected 250 Unrealized Dreams and now I have a big dilemma. Because I want to start camp  Terofar to loot  Earthborn Titan Armor  to enter to this boss I need to use Silver Prison Key.

As we know there is many items which we can get from . But the most value are: Golden Prison Key, Silver Prison Key, Bronze Prison Key and  Copper Prison Key.

What is percentage chance of getting those keys from ?

Answer 1

The percentage is not too big, but as always it depends on your luck. I had only 50 and was able to get all the keys!
