Plank Make is a Lunar spell that 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, granting 90 Magic experience per cast. 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. This does not work for sawmill coupons or if you do not have empty inventory spaces.

Spell information

Cost comparison

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

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.

An effective way to cast the spell quickly is to get the plank make spell to appear on the bottom right of your inventory (relative to the Lunar spellbook tab). This will allow you to click the Plank Make spell and the bottom right log in your inventory to avoid moving your cursor. In order to do this, you must go into to the Spell Filters settings at the bottom of your spellbook tab and check all the boxes except Show Combat Spells and Show spells you lack the runes to cast. You will need Astral runes, Nature runes, Earth runes, Law runes, and Fire runes in order to make Plank Make the 12th spell in your spellbook using these filter settings. To accomplish this without taking up any additional inventory space, you can put Astral runes, Nature runes, and Law runes in your rune pouch while having the lava battlestaff equipped.

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.
