Void Rift

A Void Rift (虚空裂隙) is a tear in the world that opens on its own, somewhere out in the wild, every hour or two. Corrupted beasts pour out of it in five waves, and when the last wave has landed a boss called the Warden steps through. Bring the Warden down before the rift collapses and everyone who fought is paid in Spirit Stones.

Unlike a Beast Tide, a rift is not aimed at anyone's home. It opens in neutral ground, anyone may walk up and join the fight at any point, and what you earn depends on how much you contributed rather than on whose side you were on. It is also on by default (Rift-Enabled), so on a server with two or more players online it happens without anyone setting anything up.

When one opens

The server rolls a random wait between 60 and 120 minutes (Rift-Interval-Min-Minutes and -Max-Minutes) each time it starts. When the wait is up, it tries to open a rift. Whether it succeeds or one of the checks below says no, a fresh 60 to 120 minute wait begins afterward.

A rift opens only if all of these hold:

The "other big event" check waits for any running Celestial Event, any Beast Tide assault, and any live Calamity Beast. A rift never takes the shared celestial slot itself, so it does not change the sky and does not stop those events from starting while it is open.

Where

The server picks a random player who is online in an ordinary world (not the Heavenly Realm, not a Sea of Consciousness, not an instance such as a dungeon) and drops the rift somewhere between 90 and 220 blocks from them (Rift-Spawn-Min-Radius-Blocks and -Max-Radius-Blocks), on ground that is already loaded. A roll is thrown out if it lands near anyone's holdings: the rift keeps clear of sect ground, Cave Abodes, Secret Realm sites and land claims by Rift-Guard-Radius-Blocks (40) plus the 35-block reach of the biggest wave spawner. If every try fails, there is no rift this cycle.

How you find out

• Everyone in that world gets a chat line: A Void Rift tears open nearby! Push back its waves, then bring down the Warden before it seals. It goes to the whole world, not just to people close by.
• A violet Void Rift pin appears on the world map for the rift's whole life, from the moment it opens until it resolves, and shows no matter how short your render distance is.
• Rift-Announce-Server-Wide (off) adds a second, location-free line, A Void Rift has torn open somewhere in the world!, but in 0.11.0 it still reaches only the rift's own world.

The fight

Waves get harder, both in what they send and in how big those beasts are:

These are the same corrupted beasts a Beast Tide uses. Each wave's spawner caps how many of its beasts can be alive at once: 12 for the first two waves, 6 for the next two and 3 for the last. Beasts left over from an earlier wave are not removed when the next one arrives, so a fight you are losing gets more crowded, not less.

Rift beasts and the Warden can kill you. Rift-Lethal is on by default; turn it off and their blows can no longer finish a player off.

The Warden

The Warden is the corrupted Cave Rex that also leads a Beast Tide as its Tide Lord, wearing a Void Rift Warden boss bar. Its health depends on how many people showed up:

Warden health = 2,200 x 1.6, plus 20% for every qualifying contributor so far, up to +120%

That is 3,520 on its own, 4,224 with one contributor, 5,632 with three, and a ceiling of 7,744 with six or more. (Rift-Warden-Max-Health, Rift-Warden-Scale-Multiplier, Rift-Warden-Health-Per-Contributor-Percent, Rift-Warden-Health-Bonus-Max-Percent. Despite its name, the scale multiplier acts on health rather than on the Warden's size.) A qualifying contributor is anyone who has reached 25 contribution points when the Warden appears, so the waves are where the Warden's health is decided.

When it steps through, players within 64 blocks (Rift-Encounter-Radius-Blocks) see a The Warden Emerges title and get the boss bar and a driving music track (Rift-Title-Enabled, Rift-Encounter-Boss-Bar-Enabled, Rift-Encounter-Music-Id), and everyone in the world is told in chat.

Contribution and rewards

The rift keeps a score for every player. Your contribution is:

• every point of damage you deal to a rift beast or the Warden, after armor and other reductions, plus
• 15 points for each wave beast you land the killing blow on (Rift-Kill-Contribution-Credit). The Warden's kill earns no bonus, because the win itself is the payout.

Only a player's own hits count: damage from a summoned spirit beast, and anything done on a sandbox profile, never adds to the score.

A win

Kill the Warden and the rift seals. The beasts still alive vanish, the pin comes off the map, and the world is told The Void Rift seals shut - the Warden has fallen, and its rewards are yours. Everyone whose contribution reached 25 (Rift-Qualifying-Contribution) is paid the single highest tier they reached:

(Rift-Reward-Contribution-Tiers, written as threshold:reward pairs.) Tiers do not stack; you get the one tier, not all of them.

Every payout is then raised by a participation bonus: +15% for each qualifying contributor beyond the first, up to +90% (Rift-Participation-Bonus-Percent, Rift-Participation-Bonus-Max-Percent). That is deliberate. A fuller fight pays each person more, not a thinner slice of the same pile. Four qualifying fighters who each reached the 120 tier are each paid 45 x 1.45, or 65 Spirit Stones.

The single top contributor also rolls a 15% chance (Rift-Reward-Manual-Chance) at one extra random technique manual.

Rewards are delivered at once to anyone online, hotbar first and then pack, with the line Your Void Rift reward settles into your bag. If your inventory has no room you are told so, and the reward waits until your next login. Offline contributors are paid the same way when they next log in. A player on a test profile has their reward held until they return to a real one.

A collapse

If 15 minutes pass with the Warden still alive, the rift collapses: The Void Rift collapses, unresolved - too little was done in time. Unlike a Calamity Beast, which pays nothing when it escapes, a collapsed rift can still pay. If the Warden had appeared, every qualifying contributor still receives 25% of what a win would have paid (Rift-Timeout-Payout-Percent), with the same participation bonus. If the rift ended before the Warden ever appeared, nothing is paid.

Either way the rift's beasts and anchor are removed, and a new rift cannot open for Rift-Cooldown-Minutes.

Running it

There are no rift commands. Nothing starts, stops or lists a rift by hand, and there is no in-game admin menu for it, so the file is the only control. Setting Rift-Enabled to false stops new rifts and hides the map pin, and a rift already open plays out. A restart clears a running rift without paying it.

For add-on developers, a rift raises public events when it is about to open (cancellable, so another mod can veto it), when it opens, when each wave is released, when the Warden spawns and when it resolves. See Events.

Configuration

Everything is in mods/Siren_Cultivation/Society/RiftConfig.json; unspent rewards are queued in mods/Siren_Cultivation/Data/RiftData.json. The full society list is on Society Configs. The keys most owners will touch:

Two more keys, Rift-World-Event-Enabled and Rift-World-Event-Asset-Id, control the world-event asset that posts the seal and collapse lines. Leave them alone unless you are replacing that asset.
