Giant ent

Giant ents are level 78 Summoning familiars. They are foragers that produce oak logs, and have the ability to convert pure essence into runes. Giant ents are also useful in the Farming skill.

Giant ent pouch
Giant ent pouch is made by using a Summoning pouch on a Summoning obelisk with 124 spirit shards, a Green charm and a willow branch in the inventory. Making the pouch earns 136.8 experience points. Using the pouch to summon a Giant ent gains 1.6 experience points, and costs 8 Summoning points.

Acorn missile scroll
Acorn missile scroll enables the use of the Acorn Missile special move for a Giant ent. Using the pouch on a Summoning obelisk creates 10 scrolls.

Acorn Missile
Acorn Missile is a special move for Giant ents, which may inflict up to 187 life points to 3 opponents, as well as drop acorns.

Currently, it hits an opponent (or anyone around the opponent) twice.

Nature link
If a pure essence is used on the Giant ent, it will turn into either an earth rune or a nature rune. However, experience is NOT gained from doing this. It is also required to use each pure essence individually on the Giant ent which can be a very tedious effort.

A good method is to mine pure essence and give it directly to the Giant ent to convert. This can yield upwards of 400 earth runes and 500 nature runes an hour if the player is proficient at clicking.

Farming
Giant ents have the potential to double yield when harvesting fruit from fruit trees, bushes, cacti, or belladonna. The average bonus is a 50% yield boost. However, you will not receive experience for the bonus yield. For example, on average, a fruit tree will give 9 pieces of fruit instead of 6, however you will only receive experience for harvesting the 6.

Trivia

 * Ents are a fictional tree-like race invented by J.R.R. Tolkien for his fantasy writings (e.g. The Lord of the Rings). They are noted for their slow and long-winded language, epitomised by Treebeard's saying "Don't be hasty." The dialogue of the giant ent may be a parody of this.
 * As with many other creatures and objects, the Giant ent's examine is a pun.
 * Even though Ents have a tertiary item of a willow branch, they produce oak logs.
 * In the Funorb game Armies of Gielinor, the Titan Ent uses the Giant Ent's image.
