ProjectE: EMC for Deeper and Darker

The add-on requires ProjectE and Deeper and Darker. Its main job is to assign EMC values to materials from the host mod, such as resonarium, warden carapace, reinforced echo shards, sculk catalyst, gloomsherds, the heart of the deep and ancient vases. Without this add-on, ProjectE cannot price those materials, so they stay outside the transmutation economy. Fixed values cover the host's core materials, and ProjectE works out the remaining items from their recipes.

The values follow the progression order of the host mod. Each later material is priced above what an earlier step can produce, so a player cannot skip a stage by transmuting ahead. Ancient vases are priced above the expected return of opening one, so repeatedly opening them does not produce a net EMC gain. Both smithing templates from the host are set to the same value band as vanilla netherite templates, which keeps duplicating a template more expensive than the template is worth.

The add-on is server-side only: the server runs it, and players join without installing it. It is published for Forge and NeoForge, with a build for 1.20.1 and one for 1.21.1. The newer build covers more items, mostly because newer host blocks, such as the sculk transmitter in sixteen dye colours, have no counterpart in the older release. The code is public, but the add-on is released under All rights reserved.
