Argus campaign is among the longest storylines in WoW, with plenty of side quests apart from the main scenario. One of them is the Class Hall line, starting at Krokuun. It consists of three parts – Krokuun missions, Mac’Aree missions, and Lightforged missions. Upon completing this side questline, you’ll be awarded the Man’ari training amulet, Mac’Aree armor set, Krokul armor set, and rarer items. Another line is the Argus Legendary Ring – it begins at Vindicaar and ends at the fight with Argus the Unmaker. Invasion points are a specific type of side quests – these missions can be unlocked after completing the Chapter 2: Dark Awakenings questline and are repeatable.
