This is a Modpack for an Origins SMP server. This will be a vanilla+ modded server pack.

Backpack Mod: Added various backpacks that add extra storage for a user!
Travelers Backpack:

Full inventory? No more!

At a time where there's a lot of mods and even more items, you'll need functional and capable backpack. Since the traveler's backpack can provide about 45 inventory slots and 2 fluid tanks, which each can store up to 4 buckets of fluid (Now even more, since it's configurable!), this backpack becomes a really good option to consider. All inventory slots and tanks can be accessed via external pipes.

Chest plate or backpack? Why not both? (Trinkets integration! 1.17+)

Traveler's backpack doesn't need any empty armor slot (or other slot, unless Trinkets integration is enabled) to be worn. Player can wear one backpack on his back at the time and it's inventory can be accessed via B (Configurable) button.

The best gear for adventures!

Here comes the Traveler's Backpack! You are able to use crafting inside of backpack's inventory or pull out the sleeping bag in any time you want! Don't worry, you won't lose your spawn point! Also worth taking advantage of handy tool slots (Tool swapping described below), which render directly on backpack. Fluid tanks in combination with Hose Item (Hose functioning described below) are good portable fluid storage.

Many new blocks, including 9 wood types and 7 new stone types

Artifacts: The items added by this mod can be found in chests in vanilla structures. All artifacts only have a few chests in which they can be found, so go out and explore! Additionally, a new underground campsite structure has been added. Mimics occasionally spawn in these campsites instead of a chests, which are dangerous enemies that attack players that get too close. Mimics always drop a random artifact when killed.
