Config Changes Made
| Mod | Config File | Change |
|---|---|---|
| Ars Nouveau | ars_nouveau-common.toml | spawnBook = false |
| The Abyss | theabyss.toml | "Spawn Book" = false |
| TA The Other Side | ta_theotherside.toml | GuideBook = false |
| Celestial Artifacts | celestial_artifacts-common.toml | giveItemsOnStart = false |
| Azukaar's Fair Difficulty | none | REMOVED 2026-05-03 (with ScalingMobs / Improved Mobs); replaced by the bespoke iridescent_difficulty mod. |
| Icarus | recipes | All default wing recipes removed. 5 new T3 recipes (diamond + phantom membrane). |
| Disenchanting Table | recipe | T1-gated (same pattern as the enchanting table: 1 book + 2 gold ingots + 2 Apotheosis gems + 4 deepslate; 2026-05-16) |
| Table of Experience | recipe | T2-gated (requires 4x thermal:steel_ingot) |
| DarkOrb Orb of Origin | recipe | T2-gated (4x steel + 4x amethyst + heart of the sea) |
| Aethersteel | datapack/config | T4 endgame. Worldgen disabled, 17 items AStages-restricted, ore replacement. |
| Terramity | recipes | 22 gun recipes removed, 64 armor pieces removed, gunsmith station removed. |
| Tetra | datapack (icraft_tetra_materials) | 27 modded metal material definitions including Blue Skies, Undergarden, F&A, and theabyss (TATOS) metals (4 live theabyss entries: garnite/knight/phantom/unorithe). Diamond hammer tier. |
| Ad Astra | recipes/config | Tier 4 space dimensions: rocket workbench locked to Tier 4, a Tier 4 gate on every planet and orbit, the Tier 4 difficulty curve, death penalty 22-30 %. Loot and space enchantments in progress. |
| Mekanism | config/recipes | Generator nerfs, 2x RF costs, Digital Miner recipe change, tool/armor removal. ERA 4 (2026-06-06): fusion output buffed (energyPerFusionFuel 15M, x1.5) and fission output buffed (energyPerFissionFuel 1.5M, x1.25) so big reactors keep up with the higher machine costs; radiation and meltdowns disabled (an over-damaged fission reactor force-shuts-down instead of exploding, which is dangerous but recoverable); new T4 stage pins on the fusion chain, SPS/antimatter, the Digital Miner and ultimate-tier facilities (intermediate machines left open). |
| Blue Skies | recipes/loot | Dusk Arc removed, Shadow Armor removed, Runic Arc boss-drop only. Diopside/Charoite/Horizonite nerfed to T2. |
| Custom Abyss-themed rings | scripts | 8 kubejs:ring_* curios form a curated T3 chain that replaces the 30 stock rings of theabyss (TATOS) (the stock rings and the arcane workbench are stripped in recipe_audit.js §K); they drop from TATOS chests and Abyss bosses (abyss_boss_loot.js). The Abyss darkness/corruption/fear/void-whispers effects fire in theabyss:the_abyss. |
| Twilight Forest | tags | Portal activator: the Codex Token I (icraft:progression_token_t1) added to the mod's own diamond (since 17 October 2026; from April to October 2026 the only activator was a legacy token nothing gave). Entry to the dimension is gated at Tier 2. |
| End (vanilla + mods) | datapacks/scripts | Dragon Exploration Gate, Eyes of Ender staged at T4 (an End Compass → End Bastion unlock is planned to replace them), 9 advancement overrides, 5 End Apotheosis affixes, entity ID fixes, Moog's End Structure loot. |
Mob equipment (mob_equipment.js) | scripts | 3-day grace, equipment/damage caps, diamond→iron mob breaking tools. (This was an Improved Mobs config; that mod was removed 2026-05-03, and the handler now holds these targets.) |
| Tectonic | config | Lower, flatter terrain: vertical_scale 0.38 (down from 1.155), ultrasmooth on, flat_terrain_skew 0.65, ridge_scale reduced. Mountains still present but much less extreme (worldgen rebalance 2026-06-06). |
| TerraBlender | config | vanilla_overworld_region_weight 9→16, which raises vanilla's share of the overworld so plains and other vanilla biomes are more common (worldgen rebalance 2026-06-06). |
| Biomes O' Plenty | biome_toggles | Lush Desert, Volcano, and Volcanic Plains turned off (desert/volcanic biome presence reduced); Dryland and Wasteland kept (worldgen rebalance 2026-06-06). |
| Towers of the Wild | config | Tower frequency reduced (36/25 → 28/20) so overworld towers are a little rarer (worldgen rebalance 2026-06-06). |
| Apotheosis (tome towers) | config | Tome-tower generation reduced to 24/14-16 (worldgen rebalance 2026-06-06). |
| LootJS | scripts | Clutter removal (horse armor, spider eyes), food reduction 70%→90%. |
| Apotheosis | config | Dimension key prefixes fixed, Overworld Affix Item generation 50%→25%. |
| Iron's Spells | loot tables | Scrolls + copper spell book added to Overworld chest loot for early magic access. |
| Walkable Cables | coremod | v1.0.1: makes Mekanism cables walkable; LocalVariableTable fix. |
| Mekanism (HDPE) | recipes | HDPE Circuit Board recipe, alternative machine recipes using HDPE components. |
| Industrial Foregoing | recipes | Latex/rubber pipeline rework: logs→latex via Create/Thermal, HDPE→dry rubber. |
| Origins | power JSONs | All 9 vanilla origins rebalanced (no lethal effects; food preferences instead of restrictions). 4 custom origins added (Witch of Ink, Artificial Construct, Witherborn, Slimebodied). No Mundane, no Human. |

Custom Mods
The pack ships custom-bundled jars (in-house source builds, bytecode-patched jars and utilities). They are listed, each with its checksum, in the pack's custom-jar manifest, so the stale-jar cleanup keeps them and replaces a copy that does not match. Highlights:
- iridescent_tetra_expansion-1.0.0.jar: bundles two
[[mods]], Iridescent Modular Spells (15 modular spell books, 12 ISS + 3 Ars, full Tetra workbench integration, BookKind intrinsic overlay, 4-slot model with lining improvements; blaze/evoker/necronomicon are first-kill drops from ISS bosses) and Iridescent Reforging (Tetra-armor extension). Item IDs keep theiriridescent_modular_spells:/iridescent_reforging:namespaces; the full ID merge into a singleiridescent_tetra_expansionnamespace is deferred to the alpha→beta step. Built viairidescent-tetra-expansion-mod/wsl-build.sh. - iridescent_origins-1.0.0.jar: Origins/races/classes (3-prompt selection on first join).
- iridescent_biomes-1.0.0.jar: TerraBlender region for cherry_river_valley + cherry_mountains.
- iridescent_codex_data.jar: Patchouli Codex book (modId
icraft). - iridescent_difficulty-0.1.0.jar: bespoke time-based per-dimension mob scaling (it replaced ScalingMobs / Improved Mobs / Azukaar's). See Systems.
- Patchouli + ars_nouveau: bytecode-patched (they need the
-noverifyJVM flag).
