Progression Gates

Progression gates

Matriochka slows down vanilla shortcuts so that each world stays meaningful. The gates are tied to your group's defeated bosses. This page lists each gate, how the code enforces it and whether the config can turn it off.

Content	Unlocked after	How it is enforced	Controlled by progressionGates
Diamonds	World 5	Diamond ore features are removed from overworld generation and diamonds from vanilla loot chests. Diamonds come from 4 Diamond Fragments (World 5 ore) at the Dark Altar	No, always on
Villager diamond trades	World 5 boss	Villager offers that involve diamonds (diamonds, diamond tools and armor) are put aside, and come back as soon as a player whose group has beaten World 5 trades with that villager	Yes
Enchanting and anvils	World 2 boss	Using an enchanting table or any anvil fails with "The runes stay silent. Finish World 2 first."	Yes
The Nether	World 2 boss	Entering the Nether sends you back to the overworld spawn with "The portal rejects you. The Nether opens after World 2."	Yes
The End	World 8 boss	Same as the Nether: "The End opens after World 8."	Yes
Elytra	World 8 boss	Elytra flight stops at once in worlds 4, 6 and 9	No, always on
Beds	Never	Beds cannot be slept in or set your spawn in any of the ten worlds ("Beds do not work inside a world. Use a Soul Cradle."). Respawn anchors do not work in the roofed worlds	No (dimension data)
Seeds and rite objects	Previous boss	A Seed can only be planted, or a rite object set down, if your group beat the previous boss	Always
Station recipes	Listed per recipe	Locked recipes are hidden in the station screen	Always
Class levels	Worlds 2, 4, 6, 8	Class Table refuses upgrades past your cap	Always

Creative players bypass the enchanting, Nether, End, recipe and class gates.

Notes

• Iron is the top vanilla material before World 5; netherite still requires diamonds, so it follows naturally.
• Karma also changes villager prices and reactions on the Surface (see Souls and karma).
• Existing diamond ore in chunks generated before the mod was installed stays in place.
