The Plank Make spell is a Lunar Magic spell that will convert one log that can normally be converted at the sawmill into a plank of the same type, but without running from the bank to sawmill. This still costs coins (as in, the spell will actually charge you money based on the type of log you are converting) but it is 30% cheaper than the sawmill operator. However, this saving is often negated by the rune cost of the spell, which is 946 coins based on GE prices for the nature and astral runes (assuming player uses a staff for the Earth runes). Plank Make is a good method to train magic and is faster experience than High Level Alchemy. The need to stay in a bank area may cause players who prefer to train other skills along with magic to be more inclined to use High Level Alchemy. Dream Mentor must be completed in order to cast this spell. Temporary Boost cannot be used.

Plank Make may be cast once per 3 game ticks (about 1.8 seconds). Including banking time, up to about 1800 Plank Makes may be cast per hour, giving about 162k magic experience per hour.

  • Casting Plank Make on Lunar lumber in the Livid Farm uses a different animation which originally was a large ball of bright light. This was later changed to be not so intense and a dimmer red colour. This was announced in Patch Notes (3 May 2011).
  • Plank Make used to have a confirmation screen for each log, but this was removed. The removal of the confirmation screen sped up the cast speed from once per 4 game ticks to once per 3 game ticks.
  • In September 2009, the cast speed was changed to 2 game ticks per cast but was later changed back to 3.
  • A player casting Plank Make can successfully follow another player as long as some time between casts is given. It is possible to walk around short distances; again leaving some time in between casts. Large distances, however, cannot be covered.
  • A player must cast Plank Make exactly 104,853 times to go from 86 - 99 Magic, and will make a loss of -57,249,738 in doing so, if making mahogany planks.
