Is your feature request related to a problem? Please describe.
The wiki lacks information, notably about the 1.12 version.

Describe the solution you'd like
Specific pages or categories on the wiki for version-specific functionality and items, such as:

• Corrupt Pixi
• Rotten Dragon Scale
• Leather of the Sea
• Cherry Peach
• Colored Feathers
• Sacred Scepter
• Battle Skull
• Runic Tenebris Frame/Core
• Ender Crystal Gem

Describe alternatives you've considered
I considered sifting through the source code to see what corrupted pixies do in 1.12, but I didn't see it as an option in the branch selection.
