Every boss now has their own theme, not sharing it with anything else. The only exception being...
(was also listening to boss 3 the ENTIRE time I was making this)
Example: Guaranteed RoD on 500th (or maybe 1000th) chaos elemental kill, or guaranteed boss trophy after deating them the 5th time.
The guide, of course, has tips that he himself mentions can be helpful if the player gets stuck.
Naturally, he has tips for many bosses including the wall of Flesh, specifically a hint at how to summon him. This is because
defeating the wall of flesh is necessary, possibly THE most necessary step to progress in the game.
“When you are ready to challenge the keeper of the underworld, you will have to make a living sacrifice. Everything you need for it can be found in the underworld.”
Now something not many of you know (but I know some of you do) is that the guide ***IS*** the Wall of flesh.
***This means that he knows that he has to die for the betterment of the world.***
