[PU4, Powers] What does Cosmic power modifier actually do?

[Refplace]

Basically its like saying Cosmic as a Power modifier is 0% IF you take one of the enhancement modifiers (Like Irresistible attack) then you can declare it as a modifier as well. This from Supers p101
Then the Modifer is explained on p26 as a PM.
If you had a Cosmic enhancement on a power and did not want it as a power modifier then most GMs would let you have a wild power or another PM.
However the things Cosmic does is pretty extreme and likely only to be a Cosmic type power. Because they essentially break even Supers Physics and do stuff most cant do.

And this was not really gone over in PU4 Enhancements since after all it is about enhancements not powers.
This is actually kinda cool.
Cosmic is +50% as a Power modifier but you can instead take one or more of the Cosmic enhancement types then your really getting a discount as its rolling up the PM into the entrancement.
However if you do not want to take one then you need the +50% to cover the Tier and other possible functions of this kind of power.
