Exspectriments
by chromonym
Exspectriments is a Spectrum addon for Fabric and Quilt that adds lab coats, liquid gems, a potion effect and several automated pigment methods.
What it does
Spectrum addon content is added through the mod: lab coats, a new potion effect, liquid gems and a process that decrafts vanilla-style gem blocks using liquid gems. A printer gains finer control over dyeing items, and a method for obtaining some hostile mob drops without fighting mobs is included. Pigments can be produced through an automated method, and a setting stops certain entities from spawning in Peaceful mode.
The mod requires Fabric API, Fractal, Revelationary and Spectrum. Both the server and every player need it, because the environment is client and server. Files exist for 1.20.1 on Quilt and for 1.21.1 on Fabric, with the latest Fabric file 0.3.0 for 1.21.1 and the latest Quilt file 0.2.0 for 1.20.1. The code is released under the GNU Lesser General Public License v3.0 only, so it is open source.
