First age equipment is acquired as a rare prize from Treasure Hunter. The items were released on the 12th of March and became available on the Squeal of Fortune on the 15th of March, with increased chances until the 18th of March.
When one item is worn, it gives a Prayer experience bonus of 1%. When all of the parts are acquired and worn, an additional 1% set bonus is given, for a total of 6%
This is the first skilling outfit, including from the Squeal of Fortune, that uses the Necklace and Cape slots. The only other xp boosting set to include a Ring is Firemaking with the Ring of fire. In addition the Gloves slot is occupied by a bracelet, which is also unique aside from the Flame gloves.
The outfit did not work with Bonus XP on a POH altar. This was fixed in an update on 21 January 2014.
