When broken down, this method combines three skills: Woodcutting, Fletching, and Magic. Each part has its own pros and cons.
Cutting yew logs is slow for both XP and money. Fletching them into longbows gives decent XP and some profit. High alching these bows costs money and gives slow Magic XP.
Overall, are yew longbows worth high alch in OSRS? The answer is no, it's not the best use of your time.
You'll make more progress by separating these activities:
- Cut teaks for faster Woodcutting XP
- Fletch darts for quick Fletching XP
- Use stun alching for better Magic XP
- Kill Zulrah for good money
This approach will level your skills faster and leave you with more gold in the end. If you need quick cash to support these better methods, you might consider options to buy OSRS gold from trusted sources like Chicks Gold rather than spending hours on inefficient methods.
The combined yew longbow method might seem appealing for multi-skill training, but the math shows you're better off specializing in each activity for maximum efficiency.
