Completionist cape

The completionist cape is the best cape in the game and is awarded to players who have "completed the game" by finishing all of the major content available. When purchased, it comes along with a corresponding hood. 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, and Dungeoneering up to 120, completed all quests, tasks, miniquests, unlocked all the music tracks, prayers, and magic spells. The cape can then be upgraded to a trimmed version after completing a list of requirements including unlocking Profound decorative armour at Castle Wars and a full statue of Dahmaroc in the player's house.

As new content (quests, tasks, accomplishments, etc.) is introduced to RuneScape, a lot of it ends up being added to the requirements for the regular and/or trimmed version of the cape, which makes it extremely hard to wear for a long period of time. If a player is wearing the cape when new content is added to the requirements, it will be unequipped and placed in their inventory or bank, depending on space.

The cape dates back to the Second Age, when it was enchanted by the mage Dahmaroc.

Requirements
Members can buy the cape and hood on the top floor of the Varrock Museum for 5,000,000 coins from the museum guard. If anyone that hasn't met all requirements tries to touch it, they will be turned into a random animal (including monkeys, squirrels and chickens) and knocked away from the cape. They will also be given a list of remaining requirements.

Regular
The non-trimmed cape can only be worn by players who have:

Trimmed
To wear the trimmed version, you will need the following in addition to the previous requirements. Note that investigating the empty cape rack in the Varrock Museum will provide a list of things still to be done.

Forms players may take if requirements are not met
Players may take the following forms if they attempt to wear the cape from the stand in Varrock Museum without the above requirements:
 * Chameleon
 * Squirrel
 * Monkey
 * Sheep dog puppy

Appearance


Like a clan cloak and a max cape, the colours of a completionist cape can be customised by using the option in the right-click menu of the cape. In the Skillcape Customiser interface, players have the right-click option on the either of the four colour palettes to get or set a certain colour via the HSL colour algorithm (hue, saturation, and luminosity).

Similar to a dungeoneering master cape, this cape leaves a white particle trail behind the owner. These particles change to gold when upgraded to the trimmed version. The particle colour is not customisable.

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. The movements of the emote however, will remain the same.

Trivia
Bought my first completionist cape. I visited the Varrock Museum and took rightful ownership of my completionist cape. Upgraded my completionist cape. After incredible effort, I unlocked the final enchantment of Dahmaroc for my completionist cape.
 * A completionist cape beats every other cape in all fields of equipment bonuses except for the following:
 * Weight, which is higher than several other capes, including the Spotted cape, the Spottier cape, and the Wicked cape.
 * The completionist cape was first mentioned in the Capes of Distinction Developers' Blog; it was referred to as the "uber cape" at that point.
 * Unlocking all the emotes is not a requirement for the Completionist Cape, for many of them must be bought with real life money and some are discontinued.
 * After the player buys their first completionist cape, their Adventurer's Log reads:
 * After obtaining the trimmed cape, their log is updated with:
 * With an update on October 2011, the particle trail of the cape was extended.
 * A trimmed completionist cape is still just called "completionist cape" as opposed to "completionist cape (t)".
 * If the player already has a customised max cape when claiming the completionist cape, then the completionist cape will automatically be customised in the same way.
 * Earning or trimming the completionist cape broadcasts a message globally.
 * The Castle Wars requirement used to be to play 5,000 games of Castle Wars, but this was changed to the current one on 9 April 2013 after player feedback that 5,000 games took too long to complete.
