This section lists all in-game units that allow for Evolution as of this writing. Many of them will require unique items that aren't found through normal means. Instead, you'll need to search for the appropriate NPC; they will often provide you with a unique objective, completing which will earn you the item. All these NPCs will be placed in the main hub area. However, some will be difficult to spot, so make sure to look thoroughly. A few NPCs might be hidden on the rear side of certain sections, while others might be located on elevated platforms.
