A Site of Power is a type of mini-dungeon in Nightingale, and completing it rewards you with the schematic for a Major Realm Card. The first one you'll likely come across is the Antiquarian Site of Power, and completing it is required for an early quest.
Sites of Power are usually easy to spot as they are generally large structures, though their appearance will vary, depending on the biome. The entrance is sometimes high up so don't worry if you don't find it right away, and be aware that you may need to raise your gear score before it will let you inside. With all that in mind, here's what to expect when you venture into your first Site of Power.
