Irony or something Trophy in Cloudpunk

You can do this as you play through the story or just wait until after you've completed the story and are cleaning up any Free Roam trophies/collectibles. You can either get the Candy Bar before or after you meet with Haldo. If you talk with him before, you'll just get a task to bring him one. If you talk with him after, you'll automatically complete the task. If you can't find a vendor that sells Candy Bars, there's one in the same area as Haldo (he's patrolling around a bit). You can find Haldo in the Waterworks (accessed via Oldtown).



After giving him the Candy Bar, the trophy will unlock.
