ArtifactOfParallel

An artifact that splits a stage's chests, Shrines of Chance, multishops and similar loot between players. Each player only sees and opens their own; anything that drops out is shared. Added together, everyone's share is about what the stage would have in a normal multiplayer run.

Everyone in the lobby needs this mod, with the same version.

How it works

• At the start of each stage, the game places loot as usual. The artifact then hands each private object to one player, so everyone gets roughly the same total value. Objects that would push someone well over their share are removed.
• Stage-placed objects (like the legendary chest on Abyssal Depths) are copied once per player when that fits the budget; otherwise they stay shared.
• Rusted Key lockboxes, Encrusted Key caches and Shipping Request Form chests belong to the player whose item spawned them.
• If a player dies or disconnects, their unopened objects become shared until they come back (revive, reconnect, or take over a Remote Operation drone).
• A Remote Operation drone can open its player's own private objects.
• Drifter can't grab, throw or Tinker another player's private objects.
• Printers, scrappers, drones, Void Seed contents and everything else stay shared.
• With one player the artifact does nothing.

Config (kaitorque.ArtifactOfParallel.cfg)

The host's settings apply, read at the start of each stage. With Risk Of Options installed, they can be changed in game.

Section	Setting	Default	Description
Private	Chests, EquipmentBarrels, LunarPods, VoidCradles, ShrineOfChance, Multishops	true	Which interactables are split between players. Chests covers small, large, legendary, category and adaptive chests.
Private	ItemBoxes	true	Item-spawned boxes belong to the item's holder
Debug	Logging	false	Log the loot split, ownership changes and interaction checks

Console commands (for testing)

• parallel_test_chests (host): spawns one small chest per player in front of you.
• parallel_debug: lists private objects on your game and their owners in the BepInEx log.

Compatibility

Other artifacts and loot mods: Parallel has only been tested on its own and with Artifact of Potential. Other artifacts or mods that change chests, shrines or shops, or how a stage spawns them (for example Sacrifice, Command, Delusion, or mods that add their own chests), haven't been tested with it. They may break the split: objects staying shared, a player getting too much or too little, or someone seeing another player's object. If you hit a problem, try without them first, and report it with your log.

• Highlight and minimap mods may show other players' private objects on the host. Mod authors can use ArtifactOfParallel.ParallelApi to check what the local player can see.
• Players joining mid-stage (DropinMultiplayer) get a share from the next stage.

Known issues

• On the host, ambient sounds of other players' hidden objects may still play.
• Pinging where another player's object is shows the ping marker (but not the object).
