Rift Portal System
Hidden portals scattered across the world, each opening into a short encounter with its own objective and rewards.
The Rift Portal System scatters hidden portals across the Overworld, Nether, and End. Rifts spawn only at night, outside, and not inside spawn regions or land claims, at a 0.1% roll per random spawn slot. Each rift can host a different event: combat waves, a defense objective, a sword-only boss, a trader, or a storm. Find a rift, open it, and pick an event before its 32-second countdown runs out.
Finding & Opening Rifts
Rifts spawn hidden. They emit ambient sound but stay invisible unless you hold the Rift Locator Compass. Holding it reveals the visible RIFT_PORTAL_INTERACT model so you can right-click on it to start opening the portal.
Reveals rifts while it is held. You can still hear rifts without it, but they stay invisible.
/mm items give [player] RIFT_LOCATOR_COMPASS 1Used on an already-opened portal to roll one random event from the six event pool.
/mm items give [player] DIMENSIONAL_TEAR 1Right-clicking a stationary rift starts a short opening cinematic of Warden heartbeats and expanding portal rings, then leaves an open portal. The open portal has a 32-second aura timer. Right-click it with one of the activator items below to choose an event, or with a Dimensional Tear to roll one at random. If nothing is used before the timer ends, the portal closes on its own.
Portal is open. Use an activator before the chat timer runs out or the rift will close on its own.
⚠ Rift Collapse. Stay Back
When a rift closes it releases a dimensional surge. Standing too close can kill you. Chat warns nearby players before the collapse, so move away as soon as the warning appears.
Portal Events
Invasion
A scaling wave defense fought against Rift Minions, Rift Scouts, Rift Swarms, Rift Hunters, and Rift Guardians, ending with a summoned Rift Colossus. The Colossus can wrap itself in a shield entity that soaks damage until the shield is destroyed. Health and damage scale with the number of players nearby.
/mm items give [player] RIFT_BEACON 1Ender Revenant
A three-phase piglin brute boss that ignores every damage source except swords, and even with a sword it takes exactly 1 damage per hit. Its own melee is scripted, not vanilla damage. Health and outgoing damage scale with the number of players nearby. Below 50% HP it also splits off short-lived copies that vanish when struck. Requires a Revenant Summoning Core.
/mm items give [player] RIFT_REVENANT_CORE 1Arcane Heart
Keep the Arcane Heart alive for a full 5-minute defense timer. Waves of Arcane Seekers move directly toward the Heart while Arcane Attackers pressure the players. Rewards scale up if three or more players are inside the defense area when the timer completes. Requires a Rift Seal.
/mm items give [player] RIFT_SEAL 1Rift Trader

/mm items give [player] RIFT_SUMMONING_CORE 1Moving Circle
A damage zone tracks a moving safe circle while three attacker types spawn to push you out: a Breeze that flings you with wind, a Blaze that fires burning shots, and Silverfish that harass at range. Standing outside the circle applies the damager mob's aura. Requires a Cyclic Boundary Sigil.
/mm items give [player] RIFT_CYCLIC_SIGIL 1Rift Storm
Summons a Rift Storm anchor that repeatedly spawns Rift Storm Creatures and calls lightning across the area for the duration of the event. Clear out or hold the ground until it ends. Requires a Talisman of Chaotic Tempests.
/mm items give [player] RIFT_CHAOS_TALISMAN 1Recipe Book & Currency
Reading the Rift Portal Recipe Book consumes the book and grants the vanilla recipe unlocks for every rift material and gear piece in the pack. It remembers the player, so a second book just tells you the recipes are already unlocked. Killing rift mobs drops Rift Portal Coins. Nine coins craft into a Rift Portal Ingot, and nine ingots into a Rift Portal Block. Trader and shop prices are quoted in these tiers.
/mm items give [player] RIFT_PORTAL_RECIPE_BOOK 1The Dimensional Tear, dimensional materials, and Portal Rift equipment recipes only craft at night. Currency, the compass, and event activators craft at any time.
