The alchemy machine is a structure you build on your Private Island that allows the Alchemy Macro to automatically brew potions. ## Materials | Block | Amount | | -------------------- | ------ | | Quartz Block | 59 | | Brewing Stand | 11 | | Hopper | 44 | | Chest | 12 | | Trapped Chest | 10 | | Magical Water Bucket | 1 | ## Step-by-Step Build Guide ### Step 1 — Build the Floor Place a **3×11 quartz block floor**. This is 3 rows wide and 11 blocks long. ### Step 2 — Add Side Rails Place a quartz block on **each side** (left and right long edges) to prevent the player from falling off the machine while using it. image-1 ### Step 3 — Place Hoppers Behind Brewing Stands Place **temporary blocks** along the further long edge of the floor (where the brewing stands will go). Then place **11 hoppers** behind these temporary blocks, sneaking and clicking on the temp blocks so the hoppers connect to them (face toward the brewing stand row). image-2 image-3 ### Step 4 — Place Brewing Stands Remove the temporary blocks and place **11 brewing stands** in their place, on top of the quartz floor. The hoppers from the previous step should now feed into the brewing stands. image-4 ### Step 5 — Place Chests Place **double chests and trapped double chests** alternating next to each other on top of the hoppers — normal chest, then trapped chest, then normal chest, then trapped chest, and so on. Alternating between regular and trapped chests allows them to be placed side by side without merging. Image ### Step 6 — Place First Row of Hoppers Place **1 row of 11 hoppers** directly on top of the chests. These hoppers face down into the chests. Image ### Step 7 — Place Circular Hopper Rows Place **2 rows of hoppers** on top of the previous row in a **circular pattern**. This creates a loop so items flow in a circle, putting water bottles across all chests below. Image image-8 ### Step 8 — Build Walls Build a **1-block-high quartz wall** around the top hopper area — front, back, and both sides. image-9 ### Step 9 — Fill with Water Use the **Magical Water Bucket** to fill the enclosed area with water. This is where you'll stand when using the Bottle Filler macro to fill water bottles. image-10 ## Structure Overview From bottom to top, the machine consists of: | Layer | Contents | | ----- | -------------------------------------------------------------------- | | 1 | 3×11 quartz blocks | | 2 | 11 brewing stands + 11 hoppers feeding into them | | 3 | Alternating chests and trapped chests (2 rows of 11) | | 4 | 11 hoppers feeding down into chests | | 5 | 2 rows of circular hoppers (items loop to distribute evenly) | | 6 | Quartz walls + water pool (player stands here and fills the bottles) |
