Ygdar Orus Li Ox

is a colorless mutation which saves the player from death once. It can only be acquired from Guillain after leaving the Prisoners' Quarters and will be subsequently locked, if not chosen then. After it activates, it will not be possible to reset its mutation slot. If the heart icon is red, the mutation is active while a rotten heart icon means that it was used.

== Notes ==
* As a new player don't hesitate to try it. The "locked" part of the description means only one run not the whole game.
* Does not protect against death by Curse or the Cursed Sword.
* The mutation's description is inaccurate, as it can be reset anytime before activation, provided if it has been picked up.
* The first use of this mutation unlocks the achievement YOLO! Or not?
== Trivia ==
* The name of this mutation, as well as its internal name, is a reference to the word YOLO, meaning "You Only Live Once".
