so i found many difrent ways where native outsiders (like syphs or ifrits etc) or classes related to them, can gain a daily spell like ability to cast planeshift to the elemental plane which allighn with their race (usaly somewhere around level 15~ like this one). but there is nothing that allow them to get back to the prime material plane!
so is this a one way trip then? why would some1 waste a feat \ try to get a class abiity to be able to leave the plane he knows and travled for so long without an ability to get back?
(especialy in case of an ap where most of the stuff he need to deal with is in this plane of existance).
edit. the only one seemingly able to get back with such abilities are the fetchlings
