NeoForge 1.21.1 addon for bertie: the Hephaestus Forge (Forbidden Arcanus 2.6.1) runs on Iron's Spells 'n Spellbooks ink instead of experience.
| Forge tier | Accepted ink | Essence |
|---|---|---|
| I | Common Ink | 40 |
| II | Uncommon Ink | 80 |
| III | Rare Ink | 160 |
| IV | Epic Ink | 320 |
| V | Legendary Ink | 640 |
Each tier doubles the previous (40 × 2^(tier−1)).
- Only the ink matching the forge's tier is consumed (wrong-tier inks sit inert, like any
junk item in stock FA —
InputSlotdoesn't filter placement; shift-click won't route them). - Removed XP sources: vanilla XP bottles (essence component stripped), Xpetrified Orb
(blocked at
EssenceDataInput; its component is kept so right-click XP redeem still works), disenchanting (ExtractEnchantmentsInputdisabled — also on Essence Utrem Jars), stored-essence items pouring EXPERIENCE (EssenceStorageInputblocked for that type). - UI: essence renamed Ink (
essence.forbidden_arcanus.experience), XP slot's glass-bottle ghost icon redrawn as the ISS ink pot (no feather) in FA's ghost style. Delivered via a force-enabled built-in resource pack (AddPackFindersEvent,Pack.Position.TOP) so the override can't lose the mod-resource load-order lottery.
Essence Utrem Jars have no tier, so an EXPERIENCE jar can be filled with any ink (right-click) and a Quantum Injector will push that essence into any forge — automation bypasses the tier gate by design of FA's jar system. The forge slot itself is always gated.
- Inks get FA's
forbidden_arcanus:essence_datacomponent (EssenceValue(EXPERIENCE, 40·2^(tier−1))) viaModifyDefaultComponentsEvent— FA's ownEssenceDataInputthen accepts/consumes them. - 5 tiny mixins: tier gate in
HephaestusForgeBlockEntity#getInput+HephaestusForgeMenu#canInput, whitelists/kills in the three stockHephaestusForgeInputimplementations. - Forbidden & Arcanus and Valhelsia Core are resolved from the Modrinth maven for
compileOnly; mods.toml orders usAFTERforbidden_arcanus so our component patch wins.
gradle build
Jar lands in build/libs/forgeink-<version>.jar.
gradle test
The JVM suite covers the ink tier policy, essence amounts, strict forge-tier matching, and the required mixin and built-in resource-pack wiring. It does not launch a client.

One exception. The bundled resourcepack override contains a modified version of Forbidden & Arcanus' Hephaestus Forge GUI texture, by stal111, re-labelled so the gauge reads as ink rather than experience. That file is a derivative of stal111's artwork, is credited to them, and is not covered by the public domain dedication. See NOTICE for the details.
