Varrock. The main reward is Varrock Armour 4. The reward is not as enticing as the Morytania Diary, this reward does not come with lots of RuneScape gold benefits. Varrock's Armour 4 primary perk is the ability to switch Varrock Teleport location from the city center to Grand Exchange. Also, getting access to Cook's Guild bank might be very beneficial for those who want to maximize the cooking speed quickly. Additionally, it:

It acts as a prospector jacket which gives you 10% chance to melt two bars simultaneously in Edgeville Furnace, Gives an ability to buy 120 battle staves from NPC Zaff, Grants 10 percent chance to mine two of any ore simultaneously.

Western Provinces. Main reward: Western Banner 4. This weapon is strange and has similar stats for combat to those of An Adamant Spear. It provides unlimited teleports to Piscatoris Fishing Colony (especially helpful during Fishing training) and a free resurrection at Zulrah (but only once per day) the ability to upgrade Void Knight The top of the Void Knight and Void Knight Bottom, allowing them to receive a an additional 3 Prayer bonus, and increased Slayer points earned from Nieve along with Steve Slayer tasks.

There are also a number of smaller advantages. Crystal Saw holds twice as many charges (which is now 56 after upgrades). Two chompy birds are guaranteed to be during Chompy Bird Hunting. You'll have 1/500 chance to get Chompy Chick's pet on Chompy Bird Hunting. 150 free Ogre Arrows from Rantz every day and much more. Members of Western Banner 4 also gain access to the locked room located beneath an arch to Ape Atoll and Hunter Masters Red Chinchompa Hunting Ground.

Wilderness. The main reward is Wilderness Sword 4. Undoubtedly, the most dangerous Achievement Diary to complete since it is located mostly on PvP areas. The advantages of finishing this Diary as well as having this item are unlimited transports into Fountain of Rune, shortcuts to buy OSRS GP Lava Dragon Isle, and Deep Wilderness Dungeon. Moneymakers will do this Diary most often to benefit from the noted Dragon Bones drops since completing Elite Wilderness tasks makes all of the Dragons that are in Wildy drop bone-specific bones only.
