Tips for Ironmen and Low-Level Players
Ironmen and low-level players face unique challenges when making mahogany planks due to limited resources. Here are tailored tips:
Ironman Strategies
- Chop Mahogany Logs: Farm logs at Ape Atoll (post-Monkey Madness I) or Fossil Island hardwood patches. Ape Atoll is the best spot, offering fast Woodcutting XP.
- Use Miscellania: Allocate workers to hardwood logs for passive collection.
- Butler Method: In a PvP world, teleport to Camelot, send logs to the Sawmill via your butler, and repeat. This is faster than manual trips.
Low-Level Tips
- Start with the Woodcutting Guild method, as it requires no quests.
- Save coins by completing low-level contracts in Mahogany Homes to earn planks or Carpenter points.
- Avoid Plank Make until you have 86 Magic, as it’s rune-intensive.
By choosing the right method and optimizing your setup, making mahogany planks in OSRS can be both profitable and efficient. Whether you’re grinding Construction, chasing profits, or completing diaries, this guide equips you with the tools to succeed. Happy planking!
