FurnaceUpgrades
\nFurnaceUpgrades is a lightweight survival plugin that lets players upgrade regular furnaces using in-game minerals.
\nEach furnace can be improved in three independent paths:<\/p>\n
Speed: smelts items faster and can trigger extra smelts
\nEfficiency: can refund input items on smelt
\nFuel: makes fuel last longer and can retain heat between smelts
\nThe plugin is designed for progression-based servers that want stronger furnaces without adding custom blocks or custom clients.<\/p>\n
How It Works
\nPlayers interact with a placed furnace and open the upgrade flow (Sneak + Right Click).
\nUpgrades are tiered and fully configurable in config.yml.
\nCosts are paid with vanilla materials.
\nFurnace upgrade data is saved and restored, including when furnaces are broken and placed again.
\nFurnace status can be shown in the ActionBar for quick feedback.
\nMain Features
\n3 upgrade categories: Speed, Efficiency, Fuel
\nPer-level costs and effects from config
\nUpgrade persistence for placed and picked-up furnaces
\nActionBar status display
\nIn-game command support (help, info, upgrade management)
\nNo client mods required
\nCompatibility
\nMinecraft: 1.21.x
\nServer software: Spigot \/ Paper \/ Purpur
\nNot intended for proxy software (BungeeCord, Velocity, Waterfall) since this is a server plugin, not a proxy plugin.
\nPermissions
\nfurnaceupgrades.use (default: true)
\nfurnaceupgrades.admin (default: op)
\nNotes
\nThis plugin modifies furnace behavior only.
\nIt does not add economy integration or custom enchant systems.
\nAll balancing values are configurable so server owners can tune progression.<\/p>\n","protected":false},"excerpt":{"rendered":"
