BileSong
by AtiredDev
BileSong brings a swamp-themed Magic and Adventure set to Fabric 1.21.8, built around blood, wormwood and silk materials.
What it does
Players meet a group of swamp-themed enemies that drop blood and silk. Hemoglobin, a blood material, can be turned into pipelines that carry items, and silk thread drops from puppet enemies that carry buffed strings. Silk blocks speed up walking, and a silken mantle absorbs one instance of damage over five seconds at the cost of lowered armour.
The mod also adds magic items: a mirror that steals effects from the target, a sword with a parry ability, bouncy potions, a decoagulator that amplifies the damage a target takes, and blood arrows that release homing projectiles on impact. Wormwood can be placed as a block, living twigs serve as crafting material, and iron nuggets can be smelted. BileSong needs Fabric API and runs on client and server, so the server and every player install it. Files are published for Fabric 1.21.8 only, with 0.1.8 as the latest build from 2026-03-30, under the MIT License.
