In this guide, we'll go over each tier 2 invention machine and the setup to maximize your daily profits. These machines are incredibly useful for making Runescape Gold even while you're not playing, so if you have the required invention level, it's a great idea to take advantage of them. Keep in mind that the profitability of these machines is based on Grand Exchange prices, so the values mentioned here are based on the end of July 2023 and may change in the future due to Divine charge costs and actual machine outputs.

↖ MK2 machines Making GP per Day

↖ Alka Miser MK2

Required Invention Level: 108

• This machine is highly popular and provides steady profit per day.
• Unlike the regular alchemizer, the Alka Miser MK2 doesn't require fire runes.
• It can process about 25 items per hour at a cost of 150 machine charges.
• You can build up to two of these machines with a fully built Jumbo Generator and Workshop, providing 200 power allotment.
• Profit per Alk is approximately 930 GP based on current nature rune prices.
• Profitable items to alch include assembly bolts, ascendry bolts, Onyx bolts (e), and enchanted Mystic fire staffs or fire battle staffs.

↖ Partial Potion Producer

Required Invention Level: 114

• This machine is currently the most profitable tier 2 invention machine.
• It can hold 13,000 vials of water and clean herbs, lasting for about two weeks of AFK gameplay.
• The profit is around 1 million GP per day (varies depending on current Grand Exchange prices).
• Making clean lantadyme potions yields over 2 million GP per day.

↖ High Capacity Plank Maker

Required Invention Level: 117

• This machine is also profitable, costing approximately 417 GP per plank processed.
• It can handle 40 items per hour, and right now u-logs appear to be the most profitable.
• Planks like uplanks and magic planks are relatively new, so their prices are subject to change.
• With careful buying and selling, you can make over 2,000 GP profit per plank, leading to around 2 million GP per day.

↖ Optimized Hide Tanner

Required Invention Level: 111

• This machine is not as profitable as others, making around 500k GP per day.
• It can turn different dragon hides into leather, offering some profit but not as much as other machines.
• Compared to the potion producer, it's not recommended to have this machine in your Invention Guild.

↖ Auto Disassembler MK2

Required Invention Level: 81

• This machine costs 40 power, making it relatively efficient.
• While it doesn't directly generate profit, you can disassemble items like u-logs for simple parts.
• By converting the simple parts into empty divine charges, you can make around 200k GP per day in profit.

↖ Optimal Setup

• Two Alka Miser MK2 machines: Profit of around 2 million GP per day.
• One Partial Potion Producer: Profit of around 1 million GP per day (depending on current Grand Exchange prices).
• One Auto Disassembler MK2: Some profit from component conversion and useful for maintaining components.

↖ Conclusion

Using these tier 2 invention machines can yield significant profits every day, even when you're not actively playing. The setup of two Alka Miser MK2 machines, one Partial Potion Producer, and one Auto Disassembler MK2 is an effective way to maximize your GP gains. Remember to check Grand Exchange prices regularly to adjust your strategy and take advantage of the most profitable items.
