Reverie Knights Tactics

This trophy requires that you earn 3 Diamonds on every playable node level across all 3 Acts by completing the optional objectives in each level. Most are very easy, such as push an enemy onto a tile, while others require some foresight to unlock the proper spells, such as putting an enemy to sleep then killing them. None are terribly difficult but since you can't replay nodes, you must make sure to get all 3 Diamonds before moving on.

Most nodes open up naturally as part of the story in the dungeon areas. But there are 2 slightly hidden nodes that only unlock after talking to NPCs in camp and opening up their quests. Make sure you speak to Halyeras and Gina to unlock their side quests.
