The Claim Stamp
One item drives the whole mod. It is a shapeless recipe (one paper, one gold nugget, one slime ball) and it sits in the Ingredients tab in Creative. It costs about what a name tag costs, so nobody has to ration them.
Stamp your name on a tool and it is yours forever, wherever it ends up
Six people share one base and one messy tool chest, and nobody knows whose Fortune III pickaxe is whose. Keepsake gives you a cheap crafting item called a Claim Stamp: put it in a crafting grid with any tool and you get the identical tool back (same durability, same enchantments) now carrying one extra line in its tooltip that says it belongs to you. That is the whole advertised mod. It is also not quite the whole mod, because a claimed tool keeps working for you after you give it away.
For a week it is just tidy. You stamp your pickaxe, your friend stamps her elytra, the tool chest stops being an argument, and the little gray line under the enchantments is quietly satisfying in the way a name written inside a coat is. Then you notice that a claim never washes off, not in an anvil, not in a grindstone, not by repairing the thing with a second one, and that the mod's own store page ends a paragraph about generosity with the words "No spoilers." And you look at your fully-enchanted spare pickaxe, and at your friend who keeps borrowing tools, and you start thinking about it.
Built for shared servers; the hidden half only fires when someone else holds your tool
New to this mod? Do these in order and you will have seen the point of it.
One item drives the whole mod. It is a shapeless recipe (one paper, one gold nugget, one slime ball) and it sits in the Ingredients tab in Creative. It costs about what a name tag costs, so nobody has to ration them.
Place any unstackable item and a Claim Stamp anywhere in a crafting grid and you get that exact item back: full durability or charge, every enchantment, and any anvil name preserved. The stamp is consumed. Because the mod attaches a small piece of data instead of replacing the item, it works on vanilla gear and most modded tools alike, including energy tools that have a charge bar instead of a damage bar.
A claimed item shows one extra line in its tooltip, in quiet gray italics: "✦ Belongs to <name>". That is the entire visible feature. No glint, no colour change, no renaming. The item looks exactly as it did.
There is no unclaim recipe; an early one was deleted on purpose. The mark survives anvils, grindstones and smithing upgrades, and it survives repairing a claimed tool with a second one in a crafting grid, which is the one route that used to strip it. Nobody can launder someone else's name off a tool.
When a player who is not the owner mines a block with a claimed tool, and the owner is currently online, a fraction of the drops is quietly rerouted into the owner's inventory before they ever appear. The default is ten percent. There is no chat message, no particle, no sound and no log line anywhere in that code path. If the owner is offline the miner keeps one hundred percent, and machines and fake players are excluded outright.
Every eligible drop credits count times the rate to an in-memory balance kept per owner and per item type, and whole items are taken as that balance crosses one. At ten percent, the tenth iron ore always pays, rather than the mark streaking for dozens of blocks the way an independent coin flip did. Carry-over is capped at eight items so a long undelivered stretch can never turn into a visible vacuum, anything that doesn't fit in the owner's inventory is credited back and paid later, and nothing is ever deleted.
Tools that shatter the surrounding blocks themselves report those extra blocks as though a piston broke them, with no player and no tool attached, so they used to be invisible to the skim. The mod now records who started a break and matches tool-less drops against it, requiring the same dimension, within thirty-two blocks, the same game tick, and never a drop that already names a different breaker. Anything outside that narrow window is simply not skimmed, which is the safe direction to fail in.
The file keepsake-server.toml holds three settings and is synced to clients on join. titheRate is the fraction skimmed per item, default 0.10, range 0 to 1. oreOnly, default false, restricts the skim to ore-type drops via a tag that also covers modded raw materials and gems. notifyOwner, default false, gives the owner a quiet dark-gray action-bar line like "+1 Raw Iron" each time a tithe lands.
Marks one unstackable item as yours, permanently, and is consumed doing it. The only item the mod adds.
Where: Shapeless craft: one paper, one gold nugget, one slime ball. Found under Ingredients in Creative.
Flavour, not rules. None of this changes how the mod behaves.
The mod's own store page describes Keepsake as a tidy little cosmetic thing (claim your gear, show your name, keep the peace on the server) and then adds that a claimed tool is still your keepsake after it leaves your hands. Some players, it observes, enjoy gifting a freshly claimed, fully-enchanted tool to a friend and seeing where the story goes. The paragraph ends: "No spoilers."
The published mod is called Keepsake and its id is keepsake. The folder it is built in is called keepsake-tithe, and the design document inside it is titled "Generous Benefactor". A tithe is a tenth part, paid to whoever the arrangement says it is owed to, forever, by people who mostly aren't consulted.
No. There is no unclaim recipe and the mark survives anvils, grindstones, smithing and grid repair. That is deliberate.
Anything that doesn't stack can be claimed, including tech-mod tools with charge bars. The mod attaches data rather than replacing the item.
It will work perfectly. Depending on the server's config, roughly a tenth of what you mine with it may end up in their inventory while they are online, and nothing in the game will tell you.
Yes, both. The server does the claiming and the skimming; the client is what draws the ownership line in the tooltip.
Set titheRate to 0 in keepsake-server.toml. On a dedicated server that file lives in world/serverconfig.
