- In order to craft one Ocram's Razor from scratch, the player would need to obtain:
- 15 Iron / Lead Bars
- 9 Souls of Light
- 9 Souls of Night
- 6 Rotten Chunks / Vertebrae
- 3 Lenses
- 30 Bones
- This item's name is a reference to Ocram, a boss exclusive to the
Old-gen console version and Nintendo 
version of Terraria, and Occam's razor, a problem-solving principle which can be interpreted as "The simplest answer to a question is the most likely to be correct." - The chest-like appearance of the Ocram's Razor could also be a reference to Pandora's box, an artifact in ancient Greek mythology that unleashed curses upon the world when its owner, Pandora, opened it out of curiosity, leaving behind only the spirit of Hope.

- Incidentally, the Suspicious Looking Skull, which is exclusive to the
- Because it is only available in a Get fixed boi world, in which the Clentaminator and all Solutions are unavailable, this item, as well as the Waffle's Iron (Mechdusa's exclusive drop), makes it impossible to obtain every item without switching between worlds.
