Contractual
by x_explotion
Contractual adds paper contracts that players craft, sign and use to bind their lives, teleport allies and claim land boundaries.
What it does
A contract is crafted with a stamp and a blank contract, and the crafting uses wax, shaven candles and a chosen colour. Once signed, the contract gives a player a fixed set of effects tied to the other signer. A Life-Link contract connects two players' souls so that their hearts are shared and a single death can take both. Someone killed while under a Life-Link contract respawns with fewer hearts for a set amount of time, and the link breaks after it has been used twice.
Another mod option handles boundaries: signing a contract lets a player mark an area by selecting two points with right-clicks, and inside that boundary other signers cannot break or place blocks. The boundary can be removed by sneaking and left-clicking one of the points. A signed contract can also teleport the other signers within range to the holder, so they travel together.
Contractual is a Fabric mod for 1.21.1 only and runs on client and server, so the server and every player need it. It is open source under the GNU Lesser General Public License v3.0 only, and the source code and issue tracker are public.
