A Construction cape is the Cape of Accomplishment for the Construction skill. It can be purchased for 99,000 coins alongside the Construct. hood from any Estate agent by players who have achieved skill mastery (level 99) in the Construction skill.
Like all skill capes, the Construction cape gives +9 to all defensive stats, and also a +4 bonus to prayer if it is trimmed, which requires a separate skill at level 99. The cape is automatically trimmed if this condition is met.
When the construction cape is equipped or in the inventory, it will allow the player to teleport infinitely to their own player-owned house and each of the portals located in Rimmington, Taverley, Pollnivneach, Great Kourend, Rellekka, Brimhaven, and Yanille.
As of 1 September 2018, there are 10,887 current members that have achieved level 99 in Construction.
