Auroral
"The sky gives and the ice remembers."
Auroral is a winter expansion mod that transforms cold biomes from barren wastelands into hubs of mystical progression. Harness the power of the Aurora Borealis to craft unique tools, armor, and magical potions without ever needing to visit the Nether.
The Aurora Event
During certain nights in cold biomes, the sky comes alive with shimmering ribbons of green and pink light. This celestial phenomenon is more than just beautiful, it is the key to Auroral's progression system.
When an aurora appears:
- Glacial Basins fill with glowing Liquid Aura
- Shimmersteel gear slowly repairs itself
- Aurora Blooms sprout on snow blocks and grow only to vanish forever come morning
Core Features
Glacial Basin
The heart of Auroral's crafting system. Place this basin under open sky in a cold biome, and during aurora events it will collect Liquid Aura. Right-click with materials to transform them:
- Unrefined Shimmersteel → Shimmersteel Ingot
- Woven Leather → Shimmerweave Fabric
- Frozen Petals → Aurora Shard
- Ice → Shimmering Ice
Shimmersteel Arsenal
Upgrade your iron tools at a Smithing Table with Shimmersteel Ingots to create powerful aurora-infused equipment:
- Shimmersteel Pickaxe → Fortune III for gems and minerals only
- Shimmersteel Axe → Right-click copper to force oxidation
- Shimmersteel Shovel → Inherent Silk Touch
- Shimmersteel Sword → Applies Slowness, executes low-HP enemies
- Shimmersteel Spear → Throwable with bonus damage during auroras
- Shimmersteel Bow → Fires Star-Shots using snowballs as ammo
Shimmerweave Armor
Crafted by upgrading iron armor with Shimmerweave Fabric:
- Goggles → Nearby hostile mobs glow through walls
- Tunic → Automatically extinguishes fire
- Leggings → Speed boost on snow, Soul Speed on soul sand
- Skates → Ice skating, Frost Walker, lava to obsidian, fall immunity on ice
Nether-Free Brewing
The Cold Brewing Stand uses snowballs instead of Blaze Powder, and Frozen Petals work like Nether Wart to create Awkward Potions. Complete your potion setup without ever visiting the Nether!
Flora & Food
- Aurora Blooms - Magical flowers that spawn on snow during auroras, harvested for Frozen Petals
- Glow Leeks - Grown on Shimmering Ice, grants Night Vision when eaten
- Frosted Cookies - A frosty treat with special effects
- Hot Cocoa - Warm up with a comforting drink
Special Blocks
- Hearthwood Log - Burns for 7 days, grants frostbite immunity nearby, and acts as an Aurora Catalyst
- Shimmering Ice - Glowing ice that never melts and hydrates crops
- Aurora Lantern - Portable light that protects against the Darkness effect
Auroral Snowlette
Use an Aurora Shard on a Snow Golem to create an adorable miniature companion! These tiny pets:
- Follow you like a tamed wolf
- Can be told to sit
- Heals when hit with snowballs
- Emits gentle aurora sparkles
Optional Integration
- GuideME - In-game guidebook with full documentation
Getting Started
- Find a cold biome (snowy plains, frozen peaks, etc.)
- Craft a Glacial Basin (Stone + Blue Ice + Iron)
- Place it under open sky and wait for an aurora
- Gather Frozen Petals from Aurora Blooms
- Create Aurora Shards in the basin
- Craft Unrefined Shimmersteel (Copper + Iron + Coal)
- Refine it in the basin to get Shimmersteel Ingots
- Upgrade your iron gear at a Smithing Table!

## Changed
## Fixed
## Added
- Shimmerweave Skates now protect you from falling into lava.** While you are falling or flying downward, any lava directly beneath you turns into obsidian before you reach it.
- A new
skates_lava_fall_scan_depthconfig controls how far below you the skates look (default 16 blocks, 0 disables). (breakinblocks/auroral#17)
- Shimmer Spear.** A long-reach piercing weapon crafted from a Shimmersteel Ingot and two sticks. Left-click stabs hit every enemy along the line, only at full attack charge. Hold right-click to charge a committed strike that lunges forward and hits harder the longer it is held. Every hit applies Frostbite; during an aurora it deals bonus damage and a stronger, longer Frostbite.
- Shimmersteel Nautilus Armor.** Crafted from Shimmersteel Ingots around a Nautilus Shell. Right-click a tamed Auroral Nautilus to equip it, shear the nautilus to take it off. It drops when the nautilus dies.
- Snow-logged Aurora Blooms.** Blooms placed on a snow layer or in powder snow, by you or by the aurora, now replace the snow at the same level and remember it. When the bloom is broken or wilts the snow comes back. Snow-logged blooms keep a visible snow base and give off faint snowflakes so they can be found under fresh snow.
- Aurora Blooms can grow on Ice, Packed Ice and Blue Ice. Silk touching a fully grown bloom now gives the decorative variant. The decorative bloom can be placed in flower pots.
- Shimmerweave Goggles now show a translucent visor over the eyes.
- Lit Hearthwood Logs ignite phantoms that enter their area and phantoms will not target players standing in it.
- Tamed Auroral Nautili within 32 blocks follow you through portals and teleports. Tamed nautili orbit closer, wild ones orbit a player holding an Aurora Shard, and at most two spawn within 64 blocks of any player.
- Glacial Basins take items from pipes and hoppers into an input slot, infuse them automatically, and push results out the bottom. Sneak and right-click with an empty hand to empty the output slot.
- Shimmersteel Ingots work as an armor trim material. Shimmersteel tools and Shimmerweave armor accept the vanilla enchantments for their type.
- Shimmer Soil accepts vanilla crop seeds.
- Shimmersteel Bow damage scales with draw strength, respects Power and Infinity, and the Star-Shot counts as an arrow.
- Shimmersteel Sword executes play a particle burst and chime and count the weapon that dealt the hit.
## Changed
- Added in-game configuration access for independent aurora sky and sound controls. Disabling aurora sounds now mutes music and start/end cues and stops active music.
- Shimmerweave Skates freeze water while standing still and no longer lose durability when turning lava to obsidian.
- Aurora music plays once per aurora on the music channel at half volume. Nautilus sounds use the friendly creatures channel.
- Snow Angels need both hands empty.
## Fixed
- Fixed Shimmering Ice hydrating farm

A compatibility and polish update. The aurora now renders correctly under Iris and Sodium with shader packs, and the start sound is quieter and no longer repeats during the same night.
## Fixed
- Aurora rendering with shader packs.** With Iris, Sodium, and a shader pack such as Complementary installed, the aurora was breaking into visible triangle facets across the sky instead of glowing smoothly. The ribbon now blends correctly through any shader pack's atmospheric pipeline.
- Aurora start sound.** Now plays on the weather sound channel at 30% volume and only once per night. Previously the sound was at full volume on the ambient channel and could replay if a Hearthwood Log and Aurora Shard forced a second aurora during the same night.
## Changed
- Minimum NeoForge version.** Auroral now requires NeoForge 21.1.215 or newer.

## Added
- Ender Bloom** — a dark variant of the Aurora Bloom. Right-click an Aurora Bloom with an Ender Pearl to convert it at the same growth stage. Mature Ender Blooms drop Aurora Ender Shards and persist forever (no daytime decay).
- Aurora Ender Shard** — dropped by mature Ender Blooms. Four shards craft back into an Ender Pearl, making a mature Ender Bloom farm a renewable Ender Pearl source.
- Aurora Bloom Decorative** — a non-crop visual variant of the Aurora Bloom for decorative builds. Crafted from a Frozen Petal and an Aurora Shard.
- Roasted Snowball** — toast a snowball over a campfire or in a furnace. Eating one offends the Auroral Nautili and suppresses wild Nautilus spawns near you.
- Sugared Roasted Snowball** — a Roasted Snowball coated in sugar. Eating one apologizes to the Nautili and clears the offended state.
- S'nore** — two cookies and a Sugared Roasted Snowball. Grants Conduit Power and resets your insomnia timer.
- Equipment and block tooltips** — Shimmersteel tools, Shimmerweave armor, and Auroral functional blocks now show in-game ability and info lines so you can read what each piece does without opening the guide.
- In-game guidebook** — a proper Auroral item registered in the mod, craftable from a Book and a Snowball. Right-click to open the guide. Replaces the previous generic GuideME book that did not appear in JEI, search, or
/give. - Restored guide content** — pages for Ender Blooms, Roasted Snowball, Sugared Roasted Snowball, S'nore, plus the Nautilus offending mechanic and Ender transformation sections.
## Fixed
- Mature Aurora Blooms now drop themselves** so they can be replanted, alongside their Frozen Petal drop. Includes a 15% chance for a bonus bloom, matching the dev branch behavior.
- Recipes now show in the in-game guide.** The recipe files in
src/generatedwere using a shorthand ingredient format that NeoForge 21.1.77 does not load, so the recipe manager indexed nothing for most blocks and<RecipeFor>lookups silently failed. Regenerated with the explicit ingredient format. - Guide page resolution** — the in-game guide failed to open with "page auroral:index could not be found" because the start page id did not include the
.mdextension that GuideME stores keys under. Removed the explicit start-page override so the default resolves correctly. - Spawn egg icons in the guide** — added missing item models for Auroral Nautilus and Snowlette spawn eggs so their textures render in
<ItemImage>tags throughout the guide. - Ender Pearl from Shards, Roasted Snowball, and Shimmersteel Bow recipe entries** in the guide — these used
<RecipeFor>(item-id lookup) with recipe-id values, so they never resolved. Switched to<Recipe>(recipe-id lookup). - Ender Bloom can now be bonemealed on any substrate it c

# Auroral 1.5.4
## Added
## Changed
## Fixed
## Docs
## Added
- The Auroral Guidebook** is now its own Auroral item with a proper recipe and a real icon. Crafting a book with a snowball still produces the guidebook, and right-clicking it opens the Auroral guide.
## Changed
- The in-game guide has been completely restyled.** Every page now opens with a large item picture and a one line summary, sections are separated by clear dividers, and headings are colored. Important sub-topics show a small inline item picture next to a colored sub-heading. Recipes appear inline beneath the relevant block, and cross-references between pages are clickable item links.
## Fixed
- The guidebook now registers as a proper Auroral item.** Previously the recipe produced a generic GuideME book that carried the Auroral guide reference internally, which meant it never appeared as an Auroral item to JEI lookups, search, KubeJS scripts, or
/givecommands. The new guidebook is a real Auroral item that behaves the same as any other. - The guide table of contents now lists every page under the Auroral heading**, each with the correct icon next to its entry. Before this fix, only the home page and a couple of others were attached to the main heading. The rest of the pages floated around the table of contents without parents or icons.
- Guide page files have been relocated** to the folder GuideME expects, which prevents the guide from failing to load when other mods that use GuideME are installed alongside Auroral.
- The Food and Drinks heading in the guide** no longer shows the literal text
&instead of an ampersand.
## Docs
- Every guide page now has a hero picture at the top, gold colored section headings, and inline cross-links and recipes where relevant. This covers the Introduction, First Steps, Aurora Events, Aurora Creatures, all Flora pages, every Shimmersteel and Shimmerweave gear page, Decorations, and Food and Drinks.
- Page ordering in the table of contents now follows category ranges, so the list reads top to bottom in the same order as the home page: Getting Started, the Aurora, Flora, Shimmersteel, Shimmerweave, Decorations, then Food and Drinks.

## Fixed
- Aurora Lanterns now drop themselves when broken instead of disappearing.
- Glow Leeks now drop a leek plus bonus seeds when harvested at full maturity, like wheat. Reap mod's right-click harvest works correctly too.
- Hearthwood Logs can be relit with flint and steel after they burn out, matching the guide.
- Shimmering Ice now hydrates vanilla farmland within 4 blocks, not just Shimmer Soil, matching the guide. Works for Shimmering Ice placed before this update too.
- The
show_aurora_particlesandplay_aurora_ambient_soundclient config toggles now actually do something. Previously both were defined but never read, so toggling them had no effect. (fixes issue #1)
