Once every ten days, the moon rises blood red, drawing out more and more powerful monsters. They will hunt you. They will find you. Do you have what it takes to survive?

Loosely based on the blood moon concept found in Terraria, Minecraft mods (i.e. https://minecraft.curseforge.com/projects/bloodmoon) and command block modules (i.e. https://www.youtube.com/watch?v=XYZ2zOtu7HE), this datapack gives a new meaning to the term "survival" in survival Minecraft. In playtesting this I couldn't survive 3 minutes with full Protection IV diamond gear, fully decked out sword, bow, and shield, and enchanted golden apples. The only way I could survive was by turning and running!

Specifically:

• On every tenth night, a chat message will appear in red reading "The blood moon is rising..." to every player (above or below ground)
  
• During that night, a red aura will appear for every player (above or below ground)
  
• Mobs will randomly be buffed. The probability that they will be buffed increases with game time
  
• Mobs will randomly spawn near each player, ignoring mob cap and light limitations
  
• Buffed mobs have a much higher follow range and fire resistance (additionally, the potion effect particles help you recognize buffed mobs. As if you needed that!)
  
• Players cannot sleep during a blood moon
  

Features I may or may not add:

• Blood moon nights chosen randomly instead of once every 10 nights
  
• Feel free to suggest more!
  

Features I won't add:

• Only mobs that spawn above ground are buffed (doing this would probably cause a lot of excess server load i.e. "lag")
  
• Mobs will only spawn nearer to players that are above ground (doing this would probably cause a lot of excess server load i.e. "lag")
  
• Red aura will only show for players above ground (not possible in multiplayer using current method, would probably cause a lot of excess server load i.e. "lag")
  
• The moon actually turns red on the night of a blood moon. This is not possible in Vanilla, as far as I know.
