Quest Bed

The Quest Bed allows a Sburb player who has reached the top of their Echeladder to continue leveling up. According to Vriska, by sleeping in their respective bed, the player may begin advancing through the God Tiers. Only John's and Dave's beds have been seen so far, but the other two kids presumably also have such beds on their respective planets. The trolls' session had HS 005011 (Quest Cocoons) rather than beds, though the idea behind it remains the same.

If a player dies on their Quest Bed, they are permanently transformed into a powered up Dream Self. For instance, John was stabbed by Jack Noir on his quest bed and transformed into a fully realized Heir of Breath shortly after. Dave was sleeping in his bed when another Dave guided by Terezi was contemplating stabbing him with the Caledscratch. Vriska urges Tavros to move her to her quest bed while she is still alive (though bleeding to death after Aradia's assault), so it seems important that the player be on their quest bed at the time of death.

When John is killed on his quest bed, his dream self is also killed in the same manner before being revived; this is due to how dream selves reflect the wounds of the real self, though when resurrecting through the Quest Bed these wounds are healed. Similarly, Vriska's dream self starts bleeding to death when her real self is. A HS 4996 (later conversation with Terezi) states that when Jack killed their dream selves, the rest of the trolls lost their chance at the god tiers.

The need to face your own death makes attaining the god tiers a difficult venture. HS 4991 (According to Terezi), the only one of the trolls to have made it to the upper levels is, to no one's surprise, Vriska (though she was simply taking advantage of her situation). As a result, John and Vriska are the only characters to ascend to the God Tiers, and neither of them willingly killed themselves. It seems to be uncommon for the average Sburb player to reach them.
