About this mod Author’s original text

ReefPacks

The Reef's backpacks. Six packs, one per biome, worn in the cape slot; each one is a real inventory that travels with the item: drop it, die with it, put it in a chest, it keeps what is inside.

Install on the server and on every client. The server refuses a client that does not run the same version (Jötunn network compatibility). Players on The Reef get it through the TheReef modpack.

What it does

  • Satchel (Meadows), Rugged Backpack (Black Forest), Bloodbag Wetpack (Swamp), Arctic Sherpa Pack (Mountains), Lox Hide Knappsack (Plains), Explorers Wisppack (Mistlands). Same recipes and upgrade costs as before; the grid grows with the pack's level.
  • Open it: inventory open, press I (changeable in reef.packs.cfg). Press again to close. Option: open the pack every time the inventory opens.
  • Weight: what is inside weighs 30 % of its real weight (server setting).
  • Carry bonus while the pack is worn (+5 to +30 depending on the pack, server setting).
  • Speed malus while a pack is worn (10 %, the same for every pack, server setting): a cape or a pack, your call.
  • Portals: a portal refuses you when a pack holds something that portal refuses, exactly like your main inventory. With AdvancedPortals the pack follows the portal tier.
  • Crafting stations see what is in the worn pack (with AzuCraftyBoxes on the server).
  • A pack cannot go inside a pack.

Coming from AdventureBackpacks

Nothing to do. The packs you already own keep their look, their level and their contents: the item names and the save format are the same. Remove AdventureBackpacks (and its Vapok library) from the profile; the two refuse to load together.

Not carried over yet: the biome effects (feather fall, demister, frost/cold, troll armour), the quick-drop key, the creature drops, the legacy iron/silver packs.

Config (BepInEx/config/reef.packs.cfg)

  • [Packs] Speed malus (10) — server, synced, hot.
  • [Backpack: ] Backpack Size - Level 1..4, Carry Bonus — server, synced.

Problems

Tell Synistro on Discord with your mod manager's log (Settings > Browse profile folder > BepInEx/LogOutput.log).

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
