Mob grinders

Depends on the rules. Spawner-heavy servers let you buy, move, or stack spawners and build compact kill rooms. Natural-farm servers reward big platforms, light control, and smart location choices, sometimes with tweaked spawn rates to make large builds worth it.

XP depends on kill credit. Manual finishing hits always pay out, but many servers nerf fully AFK XP. Some allow credited trident kills, some disable them, and others convert XP into bottles or custom rewards. If enchanting and mending matter, check how the server handles credited kills.

Low mob caps, aggressive entity clearing, strict hopper limits, and redstone throttling can all tank rates. Chunk unloading and anti-AFK rules also matter because a perfect farm does nothing when it cannot stay active. Spawner nerfs and modified spawn rules can force you into different layouts than the popular YouTube builds.

Not to start. A basic drop chute with hoppers works, and you can copy proven layouts. The skills that help most are understanding spawn conditions, light levels, and simple item handling. Redstone becomes important when you start solving real pain points like overflow, sorting, and lag control.

They chase stability and value. Storage walls, auto-sorting, and repair loops come first, then higher-tier farms like blaze, wither skeleton, guardian, or enderman depending on what the server supports. On economy-focused servers, endgame is usually profit per hour without turning your base into a lag machine.
