Completionist cape

The Completionist cape is the most powerful cape in the game of RuneScape. When purchased, it comes along with a completionist hood. As being considered the hardest cape to even wield, it can be noted as having "mastery of RuneScape." It can be bought in Varrock Museum for 5,000,000 coins from the Museum guard on the top floor by members who have all skills trained up to 99, a Dungeoneering level of 120, completed all quests, tasks, and miniquests, and unlocked all the music tracks, prayers, and magic spells. See below for complete list. As new content (quests, tasks, accomplishments, etc.) is introduced to RuneScape, these achievements will most likely be added to the requirements for the regular/trimmed completionist cape, which makes it extremely hard to wield for a long period of time. The cape combines the abilities of several other items: Like Clan Cloaks and the Max Cape, the colours of the cape can be customised by using the menu opened by right-clicking the cape.
 * Ava's Alerter: Retrieve arrows
 * Ardougne cloak 4: Teleport the player to the Ardougne monastery
 * Ardougne cloak 4: Teleport the player to the Ardougne farming patch
 * Ardougne cloak 4: Enhanced thieving abilities
 * Fire cape: Bonus damage when fighting Ice Strykewyrms
 * Bonesack(e): Teleport to the Odd Old Man
 * Spirit cape: Option to toggle the ability to save Summoning scrolls

Similar to the Dungeoneering master cape, this cape leaves a trail of white smoke behind the owner. The cape can then be upgraded after completing a list of requirements including 5000 Castle Wars games and a full statue of Dahmaroc in the player's house. The particles on the cape change to gold when upgraded, and the black dragon in the emote will become gold trimmed as well. However, the actions of the emote do not change between the two forms of completionist capes.

The cape dates back to the Second Age, when it was enchanted by the mage Dahmaroc. Anyone without the requirements to touch it will be turned into a random animal (including monkeys, squirrels and chickens) and knocked away from the cape. You will also be given a list of your remaining requirements.

Emote
Players who have managed to achieve this cape can perform an emote in which they transform into a dragon, fly up and hover in the air while burning a classic "RS" sign into the ground before landing and transforming back into a player. The RS symbol disappears when the emote is over.

If this emote is performed with a trimmed cape, your dragon form will be equipped with a set of golden dragon armour and your wings will have their webs gold-plated as well.
