Casting Plank Make on mahogany logs
Processing Moderate Members
Cast Plank Make on mahogany logs at a bank, 27 per trip. Cheaper than the sawmill per plank but the rune cost eats part of the saving; margin tracks Construction demand.
Requirements
- Skills: 86 Magic
- Quests: Dream Mentor
- Note: Lunar spellbook. Coins per cast are the 70% sawmill fee (1,050 gp for mahogany).
