Change Legendary chance to pseudorandom

[DR.]

since the way the lootsystem works (totaly random (?)) 

It's not truly random or the random definition you will see on google. 

Even random.org is not that definition as if you new some facts beforehand you could predict the outcome 

https://www.random.org/randomness/ -> RANDOM.ORG is a true random number service that generates randomness via atmospheric noise.
