Pillars of Eternity II: Deadfire – Infamous Captain Achievement Guide
Infamous Captain
Survive an attack from a mutinous crew.
Your crew will (possibly) mutiny when their morale drops to 1. Achieving this is very easy – just take away all the food and water from your ship’s holds and their morale will be dropping like crazy. You can help it along by attacking ships and surrendering during the fight – your crew doesn’t like it when you flee from inferior opponents. Some random events at sea will also allow you to drop some morale.
After your morale reaches 1, a random even will pop up. I saw at least 4 different ones. One of those events is a mutiny. Just manage your crew (talk them down, pick a fight with them) during that event and the achievement is yours. If the mutiny did not happen to you on your first try, just keep sailing around with 1 morale, it will come eventually.
