Is there some like special conditions in world?
Brandon Sanderson
Nope. You just have to be chosen by the spren. So because the spren are involved then the requirements are a little different for Roshar. But to became an Awakener, you just need to get the Breath so you could pick it up on Nalthis also pretty easily.
