These are the Diablo IV Side Quests found in the Estuar continent. Side Quests are identified in the map and the minimap as a blue exclamation mark. However, there are side quests that start from an item that drops from mobs, corpses, mine nodes, and treasure chests in the open world (outdoors) or within dungeons. This list contains YouTube videos I uploaded for each Side Quest.
