Palworld 1.0.3 Patch: Aquatic Construction Kit and Jetragon Changes

What changed in 1.0.3

Both changes push major building and endgame-adjacent content much earlier into a normal playthrough — a big deal for any server where players were previously grinding levels just to unlock water building or Jetragon gear.

What the Aquatic Construction Kit actually does

The Aquatic Construction Kit doesn't give you new building pieces — it makes your existing build menu work on water. Once crafted, you can place Wooden Foundations directly on the water's surface, along with things like Logging Sites and Stone Pits. Workbenches and chests still need solid ground underneath them, but placing a Wooden Foundation on the water first solves that.

Should you update your server?

This is a straightforward, low-risk update: it changes tech-tree unlock levels, not save file structure, so there's no meaningful migration risk. Update your server the same way you would for any patch — see our Palworld 1.0 update guide if you need the general update process, and back up your world first regardless.
