About this Modpack

The words

From The Pandemonium Institute:

In the quiet village of Ravenswood Bluff a demon walks amongst you, killing by night and disguised in human form by day. Will the good townsfolk put the puzzle together in time to execute the true demon, or will evil overrun this once peaceful village?

In Blood on the Clocktower dead players are never eliminated, every player knows something that can impact the outcome, players may enter a game after it starts, the Storyteller may give misinformation to players who are 'drunk' or 'poisoned', and the dynamic Storyteller role leads each game to a nail-biting outcome. No two games are ever the same and death is not the end...


"Clocktower" is a social deduction game that will remind you of games like Werewolf or Town of Salem. This modpack is an implementation of the game's mechanics, making it convenient to play with your friends in Minecraft.

‼️Installation

Adding this modpack to your server is slightly more involved than a regular modpack. I have linked a video guide below, but the instructions are as follows:

  • Install the modpack as you would any other.
  • Move the contents of /server/config into /config.
  • Move the contents of /saves into your server's root folder.
  • Setup Simple Voice Chat.
  • Op yourself from the server console.
  • Run /reload.
  • Run /function ct:init/yawp_reset.
  • Run /function ct:init/yawp_regions.
  • Done!

Frequently Asked Questions

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match.

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to Blood on the Clocktower without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.10). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

Blood on the Clocktower server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time.
