If you mean by giving the player DNA points after evolving a trait, unfortunately no. The Scenario Creator won't accept the minus symbol in the Trait Cost

I meant, that when the trait is evolved, all other traits only cost half the original prize.
(Trait 1 cost 50 DNA, Trait 1 with Trait cost decrease active cost 25 DNA)

No. It's not possible to do that without creating duplicate traits and making them locked unless a trait is evolved

You can make the trait activate an event that in turn activates the genetic drift multiplier and alters it, but, iirc, the genetic drift can only increase the cost of traits(scaling and it does as well scale with infected population by itself), I don't think that by making the multiplier negative you can reduce the cost of traits, but I haven't tested it

Before I asked this, I already tested this.
When activating genetic drift and setting a negative multiplier you get DNA point instead of spending them, making every trait "free to buy".

Well it depends on how low the value was. Did you try making the value -0.5?

The lowest possible values are 1 and -1.
I tried both 0.5 and -0.5 -> didn't work!
Thanks for your help anyway.

Try making the value .5 rather than 0.5 and let us know if this helps :)

It worked!
Thanks for your help Ndemic.
But why is there a difference between 0.5 and .5?
