How Plank Make Profit Works
The Plank Make spell on the Lunar spellbook converts one log into a plank per cast. It requires 86 Magic and costs 1 nature rune, 2 astral runes, and 15 earth runes, plus a sawmill fee that varies by log type: 70 GP for regular planks, 175 GP for oak, 350 GP for teak, and 1,050 GP for mahogany. Each cast gives 90 Magic XP.
At approximately 1,900 casts per hour, Plank Make converts logs into planks faster than running to the sawmill manually. The profit per plank equals the plank's GE price minus the log cost, rune costs, and sawmill fee. Mahogany and teak planks typically have the best margins because Construction training consumes them in large quantities, creating sustained demand.
Using a steam battlestaff eliminates water and fire rune costs, improving margins slightly. The calculator above factors in all costs with live GE prices.
