Pathfinder: Kingmaker

This is a side quest that you'll run into, as you progress the main story. Initiating is impossble to miss, but the conclusion required to obtain the trophy can easily be missed. All you have to do is do as the quest says. Collect the pieces of the crown. For this trophy, you need to give the crown to The Eldest known as Shyka The Many. You've met them before, charming entity. Before handing them the crown, I suggest a hard save. You'll have two opportunities to give them the crown. One on the map where you obtain the quest, and again once you've rejected them the crown, and have entered the House at the Edge of Time. Once you've handed them the crown, and cleared The House at the Edge of Time, defeat Nyrissa in combat. Don't ally with her, don't romance her, don't kill her. Just let her do what she wants with the Cup of Apologies. A cut scene will play once you enter the portal, and you'll find out how the prank that Shyka wanted to play, went. The trophy will pop and the credits will roll. This is one of the endings
