Rust

Iron swords, axes, shovels, hoes and pickaxes, along with other blocks and items, can rust over time. Rust passes through three levels labeled exposed, weathered and oxidized, and a player applies wax to halt the progression. Rusty equipment deals less damage and reduces armor protection, while a waxed piece keeps its original stats and gains extra protection.

Rusty tools carry a tetanus effect that applies when they strike an enemy, and that effect adds an extra debuff and injury to the target. Waxed tools lose their special effects but do not rust. The mod is a good fit for survival players who want a material progression that matters beyond durability, and for servers that want wax to be a meaningful upkeep choice. Rust runs on client and server, so the server and every player need it.
