Though the Dream SMP server itself is in regular survival and players can easily respawn after death, the three lives system was put into place because of the storytelling being done and a need to legitimize death on the server.
What happens if you die on Dream SMP?
When Tubbo died, he either returned back to life on his bed or his original spawn point in the middle of nowhere. Minecraft characters can return back to life as many times as they can want, but there is a catch. They feel the pain, even after they die, and they can’t heal since they don’t have any injuries.
Who killed TommyInnit?
After the trial, TommyInnit was killed by Phil.
Is the Dream SMP scripted?
Some of it is scripted and planned out, driving a larger story, but many of the reactions and circumstances are totally improvised. Like a television show or cinematic universe, Dream SMP found its audience through a series of never-ending epic battles.
