Nihlathak is encountered in the Halls of Vaught after completing the Prison of Ice quest in Act V. In Hell difficulty on battle.net he will drop the Key of Destruction, a requirement to access the Pandemonium Event.
Nihlathak's Corpse Explosion and Arctic Blast skills are the main reason he is feared among Hardcore players. When you kill one of his summoned Minions, make sure you use a skill that utilizes the corpse before Nihlathak can explode it such as the Paladin's Redemption, Barbarian's Find Potion, or Necromancer's Revive. Equipping Items with the "Slain Monsters Rest in Peace" modifier such as the Nature's Peace Ring has the same effect. In Normal and Nightmare you can also use freezing attacks to shatter the minions so they do not leave corpses. High Fire Resistance and Physical Damage Reduction/Block Rate will help against his Corpse Explosion. If you get too close, Nihlathak will use Arctic Blast on you, giving him greater advantage. Being frozen will put the players in greater danger. Having Thawing Potions or hit recovery will lessen the effects of Arctic Blast.
