so both returned individuals on Nalthis, and Szeth require investiture to prolong their existence. despite there being some visual diferences in how both returned and Szeth are described, would it be wrong to say that Szeth is a kind of returned?
furthermore, if a dead person recieves enough investiture, could they come back to life?
something i want to see in SA5 is Wit getting back the flute that kaladin lost. if im not mistaken, lift found a flute in either Oathbringer or RoW. is that flute Wit's Flute?
this probably gets asked alot, but, can someone be an awakener, surgebinder, allomancer, and/or any other magic powers in the cosmere? if so, are there any characters we have seen so far that have multiple forms of investiture? (Hoid, maybe?)
