Creatures get stronger and stronger as you progress through the dimensions. Bring friends speeds this up drastically.

If it's hard, move slower, spawns don't force respawn and it may be quite the run to return if you die, so play it safe and go slow

Boss 3 is definitely a bring your friend boss battle.
