Put a price on your friends' heads.

Blood Contracts adds player-funded bounties to your server. Pick a target, put real items on their head, and let the whole server hunt them down. Whoever takes them out claims the loot.

The server never creates a single item: every reward comes out of a player's inventory. It's made for small servers of friends (Create bases, everyone in their corner) that want a reason to go out, gear up and settle scores, without organised events or a permanent war zone.

How it works

1. Sign the contract. Press B (or /bounty gui), choose any player the server knows (online or offline), drop the reward in the slot and sign. Need more? "+ items" opens up to 9 different stacks.
2. The target is warned. Loudly. A full-screen alert: blood-red pulsing vignette, shaking title, a curse sting and a racing heartbeat. Offline targets get it the moment they log in.
3. Hunt. Sword, bow, TNT, your tamed wolf, a well-timed shove into the void or lava, or a Create Big Cannons shell from 300 blocks away.
4. Claim the blood money. Rewards wait in the board's "To claim" tab. A toast tells you, and nothing lands in your inventory unasked.

Features

🩸 Contracts funded by players, not by the server

• Real items go into escrow the moment you sign: one stack, or up to 9 different ones.
• Several players can stack bounties on the same target. The hunter collects all of them.
• Cancel your own contract any time… unless the target took damage from a hunter in the last 30 seconds (no cancelling mid-fight).
• Bounties on offline players: anyone who ever joined the server is a valid target.

🎯 Fair kills only

Smart kill attribution that never pays the wrong person. When in doubt, nobody gets paid and the bounty stays open.

• Arrows, tridents, TNT, potions: the player behind it gets paid, never the projectile.
• Tamed wolves: their owner gets paid (configurable).
• Knocked into the void, lava, a fall or fire? The last player who hit the target within 10 seconds collects.
• /kill, mobs, machines and Create deployers (fake players): nobody.
• The sponsor killing their own target does not get their item back. Other sponsors' bounties still pay them.

💥 Create Big Cannons support (optional)

Cannon shells have no owner in CBC, so Blood Contracts works out who fired:

• the player who pulled the lever, pressed the button or turned the crank next to the cannon mount within the last 10 seconds, or the player riding the cannon carriage;
• impacts, HE blasts, shrapnel, grapeshot and flak are all credited;
• a cannon fired by a redstone clock with nobody at the controls credits nobody.

Also supports CBC Enchanced Shells ("More Shells"): Mk.I-V shells, cluster munitions, rockets launched from a rocket base, missile mounts.

🔔 Scary alerts, quiet rewards

• The target gets a full-screen alert, not a chat line. Whether it names the sponsor is configurable.
• Rewards and refunds wait in the "To claim" tab, with a toast notification. You claim one stack or everything. If your inventory is full, the items drop at your feet, are reserved for you, and never despawn.

🏆 Advancements

🔒 Safe by design

• The server never creates items. At any time, an escrowed item is in exactly one place: the escrow, a pending reward, or a player.
• The server is authoritative: the client only sends intentions (target, bounty id), never items.
• Bounties and pending rewards are saved together, so a crash can't lose or duplicate anything. Items from a removed mod are kept untouched until the mod comes back.
• Backed by more than 100 automated tests (JUnit and in-game GameTests, including a real Create Big Cannons cannon being assembled and fired).

Commands

Server config (serverconfig/bloodcontracts-server.toml)

The damage types counted as "environmental" are a datapack tag (bloodcontracts:environmental), so you can extend it.

Compatibility

• Minecraft 1.21.1, NeoForge 21.1.248+. Required on both server and client.
• Optional: Create Big Cannons 5.11.4+ (with Create 6.0.x and Ritchie's Projectile Library), CBC Enchanced Shells 1.4.0+. Without them, everything except cannon attribution works the same.

FAQ

Can two friends farm each other? They can, and it gets them nothing they couldn't get by handing the item over: no item is ever created.

What if I'm offline when I win? The reward waits safely in "To claim", even across restarts.

Can I put a bounty on someone who isn't online? Yes, on anyone who has joined the server at least once.
