Opening the world

• Seed recipe (Matrix Workbench, after the Block Guardian is defeated): 1 Guardian Core, 16 Iron Ingot (vanilla), 16 Oak Log (vanilla).
• Soil: tilled World Soil 0.
• Hatching condition: Water (any water block) within 4 blocks horizontally and 1 block vertically of the seed. 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

Jungle terrain built on the overworld generator: Spore Moss on the surface, Rootstone below, jungle trees, bamboo, vines and melons. It rains here.

Block	Type	Drops
Spore Moss	Soft (shovel)	itself
Rootstone	Stone (pickaxe)	itself
Spore Bloom	Light level 13	itself
Sporite Ore	Ore (pickaxe, correct tool needed)	Sporite

The rule: Toxin

The toxin gauge goes from 0 to 100 and is updated once per second.

• Gain: +1 per second whenever you are not in water or rain.
• Recovery: -2 per second while you stand in water or rain.
• Filter Mask (head slot) halves the gain. Survivor-class gear reduces it further (see Equipment classes).
• Hits: each Sporeling hit adds 5 toxin. The Spore Queen's toxic cloud adds 15.
• Thresholds: 50 gives Slowness I, 75 adds Weakness I, 100 deals 1 damage per second.
• Antidote: -50 toxin. The Root Broth is checked by the code but eating it does not set its effect yet.

Creatures

Creatures spawn naturally in the world (regular ones in groups of 1 to 3, swarms in groups of 2 to 4, elites alone and rarer) and from spawners in combat structures. See the Bestiary for all fifty.

Snare Flower	30	5	-	Never moves. Every 3 s, if it sees you within 14 blocks, yanks you toward it.	Spores (60%), seed_rare (15%, item does not exist: never drops), Roots (25%)
Spore Bearer	20	3	-	Drops a poison cloud (radius 2.5, Poison I) every 2.5 s and runs away when you get within 5 blocks.	Spores (60%), Roots (25%)

Station: Spore Vat

Result depends on fermentation time. Crafted at the Matrix Workbench from 1 Cauldron (vanilla), 4 Iron Ingot (vanilla) (Block Guardian defeated).

How it works: Always ready. The vat ferments one step per second, up to 600 (10 minutes), and every craft empties it. What a brew yields depends on how long it fermented: fresh (under 1 minute) gives the normal amount, ripe (1 to 5 minutes) half as much again, aged (5 minutes and more) twice as much. This counts for antidotes, dishes and other brews; gear is not brewed and always comes out one piece. The Filter Mask needs at least one minute of fermentation.

Output	Ingredients	Unlocked
Antidote x2	4 Spores, 2 Glass Bottle (vanilla)	Always
Filter Mask	2 Chitin, 8 Spores, 2 String (vanilla)	Always
Root Broth x2	3 Roots, 2 Bowl (vanilla)	Always
Sporite Sword	8 Chitin, 1 Stick (vanilla)	Always
Chitin Helmet	5 Chitin	Always
Chitin Chestplate	8 Chitin	Always
Chitin Leggings	7 Chitin	Always
Chitin Boots	4 Chitin	Always
Sporite Sword	8 Sporite, 1 Roots	Always
Spore Bow	4 Roots, 12 Spores, 3 String (vanilla), 1 Chitin	Always

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

Boss: Spore Queen

500 health, 12 damage, phases at 66% and 33% of its health. Summon it with the Arena Altar. It drops Queen Core, and every player within 64 blocks gets 100 souls and credit for the kill.

Attack	What the code does
Light: Root Snare	Frontal strike: 60% damage within 3.2 blocks.
Medium: Toxic Cloud	Poison cloud (radius 4, Poison II) at the spot it aimed at; +15 toxin to players inside.
Signature: Call of Sporelings	Summons 4 + 2 x phase Sporelings.
Final phase: Cocoon guarded by nodes	At 33% health it summons 3 Chitin Guards; they and every other creature within 8 blocks become cocoon nodes, and the Queen takes no damage until all of them are dead.

Full mechanics, timings and multiplayer scaling: Bosses. Its animations, attack by attack: Boss attacks.
