The Plank Make spell requires level 86 Magic. It will convert one log that can normally be converted at the sawmill into a plank of the same type. There is still a per-plank cost - it costs 70% of the coins that the sawmill operator would charge. However, this saving is negated by the rune cost of the spell. Therefore people use Plank Make not to make money by making planks, but rather to train Magic. Plank Make is a good method to train Magic and is faster experience than High Level Alchemy. However, the need to stay in a bank area may cause players who like to train other skills along with Magic to be more attracted to use High Level Alchemy.

Plank Make may be cast once per 3 game tick (about 1.8 seconds). Including banking time, up to about 1850 Plank Makes may be cast per hour, giving up to about 166k Magic experience per hour.

Note: this many casts in one hour may be reduced by lag, mistakes (such as clicking on planks that have already been made), or distractions.
