Tips per dimension

Allthemodium dimensions

• The Mining Dimension is made for mining: ores are much more common and nobody minds big holes. It also has Allthemodium ore (Y 65–247). Set a waypoint at your teleport pad.
• The Other has ancient forests, soul-sand valleys, deep caves, Allthemodium, Vibranium, and the Piglich (in the Piglin Village). It's dangerous: bring food, healing and your best armor.
• The Beyond is an empty void dimension: no terrain, no ores and no mobs. Use it as a blank canvas for a sky base or a big build, and bring your own blocks.
• Look at a Teleport Pad with Jade to see where it leads.

Where the Allthemodium metals are

Each metal needs the pickaxe of the previous one: netherite → Allthemodium → Vibranium → Unobtainium.

Metal	Where it generates
Allthemodium	The Overworld's Deep Dark biome (below Y 10, on cave ceilings), the Mining Dimension (Y 65–247) and The Other
Vibranium	The Nether (on cave ceilings, Y 64–127) and The Other (in ancient stone)
Unobtainium	The End, only in the End Highlands biome: the big outer islands, reached through an End Gateway after the dragon fight. It sits in end stone near the island surface.

Nullscape changes how the outer End looks, but the End Highlands are still there.

The Twilight Forest

Bosses must be defeated in order: Naga, Lich, Minoshroom, Hydra, Knight Phantoms, Ur-Ghast, Alpha Yeti, Snow Queen, then the Highlands and the Final Castle. Areas you haven't unlocked yet are protected by curses, darkness and barriers. Fire resistance helps against the Hydra.

The Aether II

Falling off an island drops you into the void, or back to the Overworld if you're lucky. Carry Cold Aerclouds to break your fall and make a glider as soon as you can. The Aether II is still in alpha, so some things may change between updates.

Stellaris (Orbit and the Moon)

• You need a full space suit with an oxygen module. Watch your oxygen at all times.
• The Moon has low gravity, no air, desh and Novite, moon villages and dangerous creatures. Lunar parasites infect you: make a vaccine in the Laboratory.
• The Moon Dungeon holds the Heart of Luna and the Star Crawler Queen, whose trophies are needed for the Cosmic Core.

The Outer Lands

A maze of ancient eldritch ruins with guardians and golems. Come with your best gear. The Eldritch Warden at the end leads to the Primordial Pearl, needed for the Arcane Core.

World generation

The Overworld and other dimensions are changed by several worldgen mods:

• Terralith and Geophilic: new and improved biomes
• YUNG's mods: better caves, dungeons, mineshafts, temples, fortresses, strongholds, monuments, witch huts, End island and more
• When Dungeons Arise (and Seven Seas), Dungeon Crawl, Explorify: new dungeons and structures
• ChoiceTheorem's Overhauled Village and Towns and Towers: better villages and towns
• Nullscape: a new look for the outer End islands

The Dungeons & Structures chapter has a quest for each structure type.
