How to unlock the Feast of Kings achievement in The Hand of Merlin - Definitive Guide
You'll likely earn this through playing the game normally, however you can accelerate the process. Simply go into a town and go to the traders. The cost to buy and sell supplies should be the same, so just buy as many supplies as you can afford, and then sell them. Repeat the process and eventually the trophy will unlock!
