Just a quick post to remind you Patches is available in the Quahog Historical Society for medals.
You can see him quite early, in Rank 9, so you may wish to ignore him in the current Final Party event and just concentrate on White Suit Seamus. This means also ignoring the Questline and only placing the buildings that drop items for White Suit Seamus. These are the: “Going On A Limb” Wooden Appendages which drops Ship Wheels and the Dirty Maid Bar which drops Treasure Maps.
However there is one upside to unlocking Patches in the event and that’s you’ll get 1 Trophy for doing so, which can of course be converted to 1000 Medals.
Yes it’s time for us to gather round and take a look at all you will encounter in the Main Questline.
