Multi-faction instances often imply certain death to players, so those who are invited to such instances invariably come with the mentality of 'the sooner dead, the swifter to the springs.'
Being invited by this bizarre game to become a player doesn't mean you can die only once.
Beyond the initial adaptation period, which trains the player's basic survival abilities in the instance and the ability to confront the ghosts within, as long as one successfully clears the first instance, they can have a chance at revival.
But there's a catch to this revival.
It requires a complete corpse, no missing arms or broken legs; otherwise, you'd be missing some bits after coming back.
