Kill a Cold Eye Basilisk, get a Chilled Basilisk Haunch, and return it to Angus Stern in the Blue Recluse.
One of my most famous dishes is Chilled Basilisk in Lime Vinaigrette. But the problem is... the meat is impossible to keep fresh, and I must serve the dish tonight for a noble's birthday!
So if you can bring me a Chilled Basilisk Haunch from a freshly-killed Cold Eye Basilisk, quickly, then I will owe you a king's feast!
Cold Eye Basilisks are known to roam along the beach dunes of northwestern Stranglethorn, so you have much traveling to do. And be swift!
