Open Treasure Hunter chests from 14th November 2014 00:00 GMT to 24th November 2014 23:59 GMT and you’ll be in for a chance to win all-new crafting catalysts.

These stackable, pocket-slot items increase the speed of your hide, gem and gold/silver crafting by up to double!

Catalysts are consumed upon crafting an item, and each will also generate one of three mysterious fragments: the gem focus, leather case and metal setting.

Collect and combine the 3 parts to create the summoning focuses. Also stackable, these sit in your inventory and are consumed while infusing summoning pouches, giving you 20% extra Summoning XP!

These parts are collected depending on what you're crafting with your catalysts:

Each piece of gold or silver item crafted produces 1 metal setting

Each gem cut produces 1 gem focus

Each leather item crafted from any number of the hides (dragon hides, soft leather, hard leather, imphide, spider silk, carapace, bat wing, snake skin or yak hide) produces 1 leather case

Got too many of a particular part? Head over to the Master Crafter in the Crafting Guild. He’ll trade any excess summoning focus parts for ones you don’t have. If you don't have the level to get in, you can still speak to him for this purpose by clicking on the door.

You can also swap them with other players, or trade them on the Grand Exchange.

All regular accounts get at least one Key per day, and RuneScape members get two! You can earn more through gameplay – just visit the wiki to find out how, and to learn more about Treasure Hunter itself.

Head to our billing page to buy more Keys, redeem Bonds in-game, or simply click ‘Buy Keys’ when you’re in Treasure Hunter.
