Need an extra piece or two to complete the Blacksmith's outfit? Missing some of the Diviner's outfit? Never fear! Complete your collection this week on Treasure Hunter – from Wednesday the 26th of March, 00:00 GMT, the skill outfit bonanza returns!
Wearing each part of a skill outfit grants you a 1% increase to XP gain while training its associated skill. Wear all five parts and that increases to 6%! Usually very rare on Treasure Hunter, your chances of bagging a skill outfit – or seven – are massively boosted this week!
