Nature rune

Nature runes are runes that are used for transmutation spells. Each Nature rune contains energy properties of metabolic reactivity as such found in living creatures, primarily plants.

Information
With earth and water runes, and increasing numbers of natures, you may convert bones to edible bananas with the bones to bananas spell, or to peaches with the bones to peaches spell. You can also root your opponent to the spot with bind, or—for members—snare or entangle.

With fire runes, you may cast the Low Alchemy or High Alchemy (the most common use of the nature rune) spells to convert an item to coins, or the Superheat Item spell to smelt ores into bars without a furnace. Note that you cannot turn gold and silver bars into jewellery with only magic.

Members may purchase nature runes in the Mage Arena, Mage Training Arena, the Magic Guild in Yanille, or the Lunar Isle. Members with a Runecrafting skill of 44 or greater can craft nature runes from Pure Essence at the Nature altar and members with 91 or greater runecrafting can craft two nature runes per essence. Crafting nature runes yields 9 exp per essence and 18 exp at the Ourania rune altar. Recently, they have jumped to become one of the five most traded items in the Grand Exchange.

Runecrafting
The teleport to the Graahk hunter area on Karamja offers a very fast way to make Nature runes. This can be accessed by left-clicking 'interact' on the Graahk, then clicking "Teleport." After teleporting, it only takes about 30 seconds to reach the Nature altar, which is a few seconds faster than the average time it takes to reach from the Abyss. With four Runecrafting pouches, complete trips to the Nature altar can be done in 60 seconds, allowing almost 4500 single natures to be crafted per hour. On the downside, each Spirit Graahk only lasts 49 minutes.

Drops
For non-members, the main source of nature runes is non-player characters that drop them (such as Guards, Dark Wizards, Flesh Crawlers or Cockroach workers, as most monsters that drop runes may occasionally drop nature runes. There is also a lava-surrounded island in high level wilderness, south east of the demonic ruins, where nature runes may be telegrabbed from a spawn. Each telegrab yields 3-4 nature runes.

For members, the best source of nature runes through drops are Basilisks; They will drop from 15 to 37 nature runes at a time. They have a higher combat level than dark wizards, and it is recommended you have a combat level of 70 to make their demise easier. A Slayer level of 40 is required to kill them, as is a mirror shield.

Trivia

 * The most nature runes required for a spell are 4, for the Entangle spell.
