In Palworld arrows take about 1.5 seconds to produce for a Pal with Handiwork Level 2 (i.e. Robinquill) at a High Quality Workbench, and produce 2 EXP for the Player and each Pal (on Normal, but varies by your Difficulty Settings) each time.
Basic Steps to Arrow EXP Farming
- Build A Logging Site, a Stone Pit, 2 Wooden Chests, and 4 High Quality Workbenches
Start off by building a Stone Pit and a Logging Site for farming Wood and Stone. Make sure to have Pals with the Transporting Work Suitability to move these resources to storage. - Place 3 Pals for Logging and 3 Pals for Mining
Try to get Pals with higher levels in the Lumbering and Mining Work Suitabilities to boost the production of Wood and Stone. Having them ensures that you will quickly have enough resources for crafting arrows. - Leave Your Base and Continue Playing
At this point, you can go back to exploring the open world while resource production is onging at base until the next time you need to return. Always check that your Wood and Stone production are going smoothly before leaving the base. - Place Pals at Each of the 4 High Quality Workbenches
With the Wood and Stone farmed at base, line up production of Arrows on each of the High Quality Workbenches, dividing the maximum number you can make by 4 and assigning that number to each. - Leave Your Base and Continue Playing
Once you have your Pals set to craft Arrows, feel free to do anything else or head out and explore while waiting for them complete their jobs. - Return to Your Base and Reset the Cycle
After playing for some time, return to your Base and take all the Arrows. If these Arrows have not been already stored in Wooden Chests by your Pals, take the newly made Wood and Stone from the Logging Site and Stone Pit and put them in storage.
