To craft Buck Capsule A, you need to gather specific materials. This medicine is purple quality. It heals 891 HP right away. If you put it in your tactical slot, it will heal you automatically when your health is below 60%. You should start by building a farm for the powder.

Building the Flower Farm

Place your farm in an open spot in your base. Start with a Seed Picking Unit. Set its arrows to point from left to right. Put a Planting Unit two blocks away. Then, put a Shredding Unit one block past that. Finish the line with a Protocol Stash.

Connect the machines by running two Conveyor Belts from the picker to the planter. Run one belt from the planter back to the picker so the farm stays active.

Put your Buckflower or seeds in the seeding unit. It will double over time. Once it is full, run belts into the shredder and then to the stash. Use two Electric Pylons for power.

Setting Up the Factory Wall

You need five Depot Unloaders in a row for the main build. On the right side, place two Shredding Units. Put a Grinding Unit in front of them. Further down, add a Refining Unit facing from right to left with a one-block gap. Then, add a Molding Unit to make the bottles.

On the left side, put another Grinding Unit in front of the top unloaders. Place a Filling Unit to mix the medicine. Finish with a Protocol Stash. One Electric Pylon in the middle will power everything.

Configuring the Materials

Set your unloaders to pull the right items. From right to left, the first two should be Ferrium Ore. Make sure you refine this ore at an outpost.

The middle unloader should be Sand Leaf Powder. The next one is Buckflower Powder from your farm. The last one on the far left is another Sand Leaf Powder output.

Both Grinding Units need Sand Leaf Powder. Link the Buckflower Powder and its grinder to the Filling Unit. On the other side, link the Ferrium Ore shredders and grinder to the refinery. The refinery goes to the Molding Unit for steel bottles. Finally, run the bottles into the Filling Unit.

Managing Your Production

This setup makes one Buck Capsule A every 20 seconds. It is best to let it run while you are away or sleeping. By morning, you will have plenty of healing items. This simple version saves space and provides enough for most players.
