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

[Lamech]

You get all the advantages in powers, which are in fact pretty nice.

Suppose you have from your cosmic power the following: Talent: gardening, flight, regeneration and DR.

Now due to a string of bad luck you end up in a different body, get lobotomized, all of your opponents somehow get cosmic on their damage, and you get hit with something that prevents healing. Ending up in a different body does nothing. Getting lobotomized would strip a normal person's talent, but not yours. Normally those cosmic attacks would go right through you're DR, but your DR works just fine. Also your regeneration keeps on ticking.

Also in general normal powers face things like crippling or what not to balance out the cool options. The suggestions for cosmic powers include nothing of the sort. The suggestion is you just get cool tricks.
