But when you put the use of that spell into the DND ecosystem you are using ask yourself, what is the god of death going to do when he/she finds out you are avoiding your fate? Remember these high level spells are "reality" altering or "breaking the rules" of some god or even the creator. Wizards are powerful because their spells can change reality. There are entire races of outsiders who's job is to protect the flow of reality. If it were the greek pantheon the moment you wake up on your body, I'd imagine a guy whispering to hades, and then his reply "Release the Furies!". Or it's common magic for high level mages and all the other high level mages, rich mages, rich nobles, rich thieves etc, have all been waking up in thier prepurchased bodies and our mage who thinks he's smarter than everyone else is going to have fun at the DM's expense.
