Strategy
Lord Aldric Jitan linked his lifeforce to his Royal Guards, granting him unholy immortality until all of his guardsmen are dead. The demonic powers guiding his actions also imbue him and his guardsmen with 50% all resistances and the ability to harmlessly deflect a percentage of incoming attacks. The guardsmen are tougher than anything that came before and will heal themselves, inflict tri-elemental damage and summon guard towers that will pummel the living daylights out of you if you stand still for too long. Keep moving and the towers will vanish behind you. When any of the enemies dies, the dark forces reclaim his spirit, creating a vortex of magic that should be given wide berth.
Reward
Defeat Lord Aldric Jitan on Destruction difficulty to get the Moon of the Spider (1/4 chance).
Strategy
As a former Vizjerei in life, Quov Tsin wields the elements. His most devastating attack is a streaming blast of fire, cold and lightning bolts powerful enough to annihilate any hero in a moment. In melee combat, he may use a fire, cold and lightning nova combo that causes massive destruction at close range. Prepare for this battle by equipping resistance items to counter his ability to pierce resistances, and try to find some absorb items to further cut the damage. His contingency spells protect him by teleporting him to safety when struck by any attack. Stay near cover in case he appears too close for comfort.
Strategy
Astrogha does not usually fight his foes directly, but he does not need to. His summoned Spider Statues serve as gateways for his personal swarm, belching waves of crawling Darklings from the depths of the void. Deal with them quickly, but do not touch the statues! They are protected by one of Astrogha's devious tricks: when destroyed, they will both rejuvenate Astrogha and unleash a curse that cripples the assailant causing a swift death. If left alone, they will eventually collapse on their own. Astrogha also possesses a very powerful but close ranged Frozen Orb attack and has warding spells that teleport him away when damaged, courtesy of Quov Tsin's mages. Another dweomer copied from Quov Tsin during centuries of fighting side by side at the head of their respective legions is the warding spell that renders Astrogha immune to all attacks. This is cutting edge magic and therefore still fails from time to time, allowing you to get some hits in.
