Decreased Legendary Chance
I felt that the spawn rate of Legendary enemies was too high, so I’ve decreased the spawn chance for each difficulty by a factor of 5.
Very easy 0.25 => 0.05
Easy 0.5 => 0.1
Normal 1.0 => 0.2
Hard 1.5 => 0.3
Very hard 2.0 => 0.4
Due to the somewhat immeasurable nature of this patch, I consider V1 untested.
If you want more control over the specific spawn rate or you want to stop Legendary enemies entirely then I recommend this mod: Customize Legendary Enemy Spawning.
