Sous chef's trousers
A reward from the Squeal of Fortune, sous chef's trousers provide a 1% xp boost whilst training the Cooking skill. This bonus only lasts for 30 days after being claimed, though, counting down irrespective of whether the player uses the item or not (after which it is left as a cosmetic one) - though its lifetime can be extended by using either skill set recharge (1 day) or skill set recharge (7 days)s.
When the complete sous chef outift is worn (the other members of which being the sous chef's shoes, sous chef's toque, sous chef's mitts, and sous chef's jacket) - the player will receive a combined 5% xp boost.
This item can be converted to 15,000 gold coins on the Squeal of Fortune, but cannot be dropped or traded - only destroyed. Players can reclaim theirs in such a case from Diango in Draynor Village.
