The Plank Make spell requires level 86 Magic and the completion of Dream Mentor. It will convert one log that can normally be converted at the sawmill into a plank of the same type. There is still a cost to convert a plank in addition to the runes to cast the spell: 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 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.

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.

Alternatively, players can cast the spell once and they will automatically make the rest of the planks in their inventory, although this is three ticks (1.8 seconds) slower and results in slowing the process down by a bit with the benefit of being lower effort, giving up to 90,000 Magic experience per hour.
