Wax World is an area that can be accessed by going back to the starting room after beating the boss in the Gilded Halls. It contains enemies such as Wax Knights, The Unfinished Ones and Melted Wizards.
The Puppet NPC appears on this floor, sitting on the ground whereas they are standing in the Gilded Halls. Their dialogues remain the same.
This area's boss is the Flesh Golem.
Access
After defeating the Gold Wizard in the Gilded Halls, a message appears saying something has changed. A community guide says to use The Grand Jump to leave the boss area, go back to the starting area (where the Puppet was), and take the new portal. The same guide calls this floor the "Waxen Temple". A forum commenter notes that leaving a boss room with the Grand Jump works and appears to be intended.
Defeating the Flesh Golem here opens the portal to Ending 4.
- In a thread answered by the developer, the second portal spawns in the starting room of the Gilded Halls after its boss, behind where you teleport in, which is why players miss it. Talking to the doll NPC there is what opens the way.
