If a level 20 [Mystic](https://media.wizards.com/2017/dnd/downloads/UAMystic3.pdf) character dies, his psionic ability has a chance to bring him back to life 1d3 days later on the same plane of existence. How often can a Mystic do this? Is it every time they *die* until they fail a DC 10 roll? Or is there some other limit to it?

> 
> If you die, roll a d20. On a 10 or higher, you discorporate with 0 hit points, instead of dying, and you fall unconscious. You and your gear disappear. You appear at a spot of your choice 1d3 days later on the plane of existence where you died, having gained the benefits on one long rest.
