Echomist: Core
Echomist: Core adds sculk-themed blocks, potions, echo shard armor trims and sharpened axes to Fabric games on 1.21.1.
What it does
Sculk bricks, tiles and chiseled sculk are added as placeable blocks, and sculk bricks and tiles come with matching stairs, slabs and walls. Sculk pillars are included as well, so a build can mix sculk variants in one design.
Potions of Silence are brewed using a sculk sensor. While a player is under the effect, sounds made by entities such as walking, running and eating are muted. Echo shards serve as armor trim materials, so armor can be decorated with a sculk-based trim. Axes are slightly retextured and sharpened.
The mod is built for Fabric and runs on the client and the server, so both need it. Files are published for 1.21.1 only, with 1.0.0 as the latest Fabric build dated 2026-01-05. Source code and an issue tracker are public, and the mod is not open source; it is released under All rights reserved.
