The Plank Make spell requires level 86 Magic and completion of the Dream Mentor quest. It will convert one log that can normally be converted at the sawmill into a plank of the same type, costing 70% of the coins that the sawmill operator would normally charge.

Plank Make may be cast once every three game ticks, or 1.8 seconds. Including banking time, up to about 1,850 Plank Makes may be cast per hour with optimal rates, giving up to about 166,000 Magic experience per hour. People generally use Plank Make not to make money by making planks, but rather to train Magic, resulting in faster experience than casting High Level Alchemy.

Players can also let the spell automatically cast, resulting in a new plank being converted every 3.6 seconds, and giving up to 90,000 experience per hour with minimal effort.

Casting this spell 20 times on mahogany logs within the Varrock sawmill is a requirement for the elite Varrock Diary.

When the player casts Plank Make while having sawmill vouchers in their inventory, an extra plank is made per log.

Spell information

Cost comparison

The cost to convert logs is reduced, but this savings is often negated by the rune cost of the spell.

Log		Plank		Cost in coins
				Plank Make	Sawmill
	Logs		Plank	70	100
	Oak logs		Oak plank	175	250
	Teak logs		Teak plank	350	500
	Mahogany logs		Mahogany plank	1050	1500

Cost per plank

The below cost analysis assumes the use of a staff that supplies earth runes.

Item		Materials Required	Material Cost	Profit/Loss	GP/XP
	Plank	2 1 70	420	−69	-0.77
	Oak plank	2 1 175	547	16	0.18
	Teak plank	2 1 350	924	83	0.92
	Mahogany plank	2 1 1,050	1,840	418	4.64

Training

Players can cast the spell once and will automatically make the rest of the planks in their inventory, although this is three game ticks (1.8 seconds) slower than manually casting. This method gives up to 90,000 Magic experience and converts up to 1,000 planks per hour. This rate assumes perfect banking times; more realistically, players choosing to AFK train can expect around 75,000 experience per hour with minimal attention, checking every 30 seconds or so to determine when to bank.

Supplementing spells

Several spells in the Lunar Spellbook have a 0-tick delay when casting, allowing players to immediately cast Plank Make after. At level 82, players can cast Magic Imbue, which has a ten-second cooldown, and at level 94, players can cast Vengeance, which has a cooldown of 30 seconds. The following table shows potential experience per hour with consistent on-time clicks, and assumes that the rune pouch and an earth staff of some kind is used.

Experience per hour

Method	Plank Make only	Plank Make and Magic Imbue	Plank Make, Magic Imbue, Vengeance	Time between clicks
Casting all spells manually	165,000	185,000	200,000	1.8 seconds
Casting after cooldowns	85,000	105,000	115,000	10 seconds
Casting once per inventory	85,000	88,000	95,000	90 seconds
