You can trigger it by just sacrificing 4 characters equipped with 2 trinkets on their slots. This event will stay on the map until you clear it. After you lose 8 trinkets (with dead heroes or in-town activities), you can fight the Shrieker to get your lost treasures back.This event can happen after week 42, appears only once and will be available on the map until you clear it. During A Thief in the Night event, when the Shrieker steals 8 random trinkets from the trinket inventory.It will expire if you don’t clear it on the same week when it appears, but it can happen multiple times during the campaign, even if you already acquired all Shrieker trinkets (in this case the quest reward panel will be empty). During the Shrieker’s Prize event, where you can hunt the Shrieker in order to get one of its unique trinkets.The Shrieker can appear following 3 different events: Instead, you only have to worry about keeping your team alive until the end of round four in which the shrieker escapes using his Shrieking Flight attack on his last turn, giving you the mission success. The trick to all of this is that you don’t even need to kill this boss. The reason I choose him it’s very simple it can be encountered very easy in the early or late game and no dungeon must be completed due to the battle against him starts just after you enter his event. On the Shrieker’s last turn during Round 4, it will use Shrieking Flight, dealing 50 stress damage to all heroes before flying away, ending the battle. It is fought alongside its Nest, both of which take up two slots. The Shrieker is a giant black bird-like Eldritch/Beast Event Boss, similar to a crow, found in the Weald. Both achievements can be done easily and with minimal effort using the The Shrieker Boss.
