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 major content available. When bought it comes 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, much of it is added to the requirements for the regular 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. If their inventory is full it will be placed in their bank.

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

Other abilities
The cape combines the abilities of several other items:
 * Ava's alerter: Retrieves arrows
 * Ardougne cloak 4: Teleports the player to the Ardougne monastery
 * Ardougne cloak 4: Teleports the player to the Ardougne farming patch
 * Ardougne cloak 4: Enhanced thieving abilities
 * Fire cape/TokHaar-Kal: Bonus damage when fighting Ice Strykewyrms
 * Spirit cape: Option to toggle the ability to use 20% less summoning special energy when using scrolls. You must use a Spirit cape on the Completionist cape to unlock this function.

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 cape, 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.

Wearing the completionist hood and using the untrimmed completionist cape's "features" menu while in your inventory will show an option to remotely check the trimmed requirements you still need in your chatbox in-game.

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, the dragon is equipped with a set of golden dragon armour and the wings have their webs gold-plated. The movements of the emote 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.
