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).
