Opening the world

• Recipe of the Storm Rod (Matrix Workbench, after the World 3 boss (Grand Jailer) is defeated): 1 Jailer Core, 8 Dungeon Key, 8 Sealed Fragment.
• Rite: Set it on top of a lightning rod under the open sky. It opens during a storm, or at once when fed a Storm Essence. See The way into each world.
• Arrival: a Threshold platform at the centre of your group's parcel. The boss arena is 160 blocks south (positive Z).

Terrain

The rule: Wind

Wind and lightning, timed on the server clock.

• Gusts: every 30 seconds. A warning appears 2 seconds before. If you can see the sky and are not sneaking, the gust throws you sideways (horizontal speed 0.6 to 1.4) with a small lift. The direction turns from gust to gust. Sneak or take shelter.
• Lightning: every 45 seconds while you are under the open sky. Sparks mark a spot within 4 blocks of you 3 seconds before the bolt lands there. Step away.
• Elytra stop working in this world until your group has beaten the World 8 boss.
• Answers: Glider, Grappling Hook, sneaking, roofs.

Station: Lightning Forge

Needs a lightning strike or storm essence. Crafted at the Matrix Workbench from 2 Lightning Rod (vanilla), 4 Ash Ingot, 4 Sealed Fragment (World 3 boss defeated).

How it works: Stores charge, up to 8: +1 every 10 seconds during a thunderstorm when the sky is open above it, or +2 for each Storm Essence you hold against it. Each craft uses 1 charge; crafting with an empty forge burns a Storm Essence from your inventory automatically, so the forge shows as ready when you carry one. It also makes Lacquer Layers for layered armor (see Nesting systems).

Output	Ingredients	Unlocked
Glider	8 Ray Membrane, 4 Stick (vanilla), 2 Storm Essence	Always
Grappling Hook	2 Celestial Crystal, 8 String (vanilla), 3 Iron Ingot (vanilla)	Always
Cloud Fruit x2	2 Apple (vanilla), 1 Storm Essence	Always
Lacquer Layer x2	1 Celestial Crystal, 1 Storm Essence, 2 Honeycomb (vanilla)	Always
Lightning Lance	8 Celestial Crystal, 1 Stick (vanilla)	Always
Celestial Helmet	5 Celestial Crystal	Always
Celestial Chestplate	8 Celestial Crystal	Always
Celestial Leggings	7 Celestial Crystal	Always
Celestial Boots	4 Celestial Crystal	Always
Storm Censer	4 Storm Essence, 2 Celestial Crystal, 2 Ray Membrane	Always
Storm Javelin	3 Celestial Crystal, 3 Storm Essence, 2 Stick (vanilla)	Always

Every weapon, tool and armor piece crafted here gets a random class (see Equipment classes).
