The first time you complete a card, you will be given a Skill Card Deck that will display which cards you have completed. You’ll need to finish the Skill Card you are working on before you move on to the next. The cards are prismatic, but once you have completed a particular skill you won’t be able to go back and complete the same skill again.
If you can complete all 26 cards within the 12 day promotion, you can cash your Skill Card Deck in straight away to receive an XP reward in a skill of your choice. If you have not completed all 26 cards you’ll still be able to cash the deck in for a slightly smaller XP reward, also in the skill of your choice.
After the 12 day Ace of Trades period ends, you still have up to 1 month to work on any Skill Cards you have remaining and you can still earn your XP reward. You’ll no longer be able to obtain new Skill Cards from Treasure Hunter, though.
Everyone gets at least one Key every day, and RuneScape members get two! You can also get your hands on more through gameplay – just visit the wiki to find out how, and learn a little more about Treasure Hunter at the same time.
You can also buy more Keys via the website, redeem Bonds in-game, or just select ‘Buy Keys’ when you’re in the Treasure Hunter.
