Ultimate Mob Farms
Ultimate Mob Farms adds soul-based mob farming to Fabric and NeoForge, with gems, compact spawners and farm blocks for players who want automated mob drops.
What it does
Soul gems are emptied by killing a mob with the gem in hand, which traps that mob's soul inside. After enough souls are trapped inside it, a soul gem becomes full, and a player can then apply it like a spawn egg to set which mob the gem produces. Compact mob farms hold a spawner's output in an internal inventory that cannot be opened directly, so items are extracted with a hopper or another method. Drops are limited to a stack of 64 per item type, and anything beyond that is voided once the inventory fills up. Experience conversion can be adjusted in the config, along with which mobs trapped souls can produce and which tier a farm needs to contain them.
The mod requires Fabric API on Fabric, Loot Table Modifier and MonkeyLib538 on both loaders. Item Descriptions shows extra text on items when Shift is held over them, Reliable Recipe Viewer lists the added recipes, and Mod Menu serves as an optional companion. Colors for the items are changed through datapacks, and a few drops are available only from the compact farm. Every player and the server need a copy of the mod. It is open source under the MIT License and is published for 26.1 – 26.2.
Key features
Craftable spawners
Spawners can be crafted and upgraded, turning a single block into a compact mob farm.
Soul gems
An empty gem fills with the soul of a mob that is killed while the gem is held, and can then change a spawn egg's target.
Tiered containment
Different mobs need different farm tiers, so higher upgrades hold more mobs in a compact farm.
Configurable experience
Experience conversion, trapped mob settings and farm tiers can be changed in the config.

Ultimate Mob Farms adds all the things you may need for mob farming. This mod has integration with Reliable Recipe Viewer, and I recommend using it to see the added recipes. All items also have descriptions visible by holding shift while hovering over the item when using the Item Descriptions mod.
