Players who have played Diablo 2 have a deep impression of an NPC in Act 5, and this person is Nirasek. As a member of humanity, he chose to betray humanity and gave the King of Destruction the convenience of passing through the Sacred Mountain of Arret, but the player was blocked at the door of the World Stone Fortress. I believe that every player who was tortured by three ancient people at the peak of Yaret hated this NPC so much that he was itchy. But in fact, Nirasek also has his own difficulties. His fear of Barr made him hope to make peace with the King of Destruction to save himself and his tribe from the destruction. However, his choice eventually made him become a villain and inevitably led to his death.

Nilasek
NPC introduction
In the game, Nilasek will introduce to the player that he is an elder of Harrogas and has the power of a necromancer. But unlike the real necromancer, Nirasek did not believe in the ancestor of the necromancer " Rasma ", but because of his special status as an elder, he was able to master the skills of the mage so that he could hold worship rituals to communicate with ancient people.

Character background
When King Bar of Destruction had not yet touched the northern territory of the barbarians, a group of barbarian elders gathered around Harrogas to impose ancient druid protective spells on the town, and Nirasek was one of these elders and the only surviving elder members. But when Barr was under the savages' city block, Nirasek chose to reach a shameful agreement with the King of Destruction. In this agreement, Nirasek will hand over the "remnants of ancient people" - the most precious sacred relics of the barbarians to Barr, so that they can be unblocked at the peak of Yareth without the challenge of three ancient people. And as a condition of exchange for the agreement, Nirasek hopes that Barr and its demon army can let Harrogas go.
Nilasek will exist as an NPC in the leftmost corner of the main city of Harrogas before the player completes the third mission of "Ice Prisoner" in Act 5. When the player talks with him, he can feel that his personality is more aggressive and extremely extreme. Even when dealing with his own savage compatriots, Nirasek has no good attitude. Nirasek was more willing to focus on his own acre of three-point land than what the human people who were worried about him were doing. In the later mission briefing, players will know that Nirasek kidnapped Anya and locked her into an ice prison located in the crystal channel scene. And while the player rescued Anya, Nirasek fled from Harrogas.

talks with Nirasek
After completing the "Ice Prison" mission, the player will receive a task called "Shameless Betrayer of Harrogas" in Anya, and the mission goal is to kill the escaped Nirasek. The player will encounter Nirasek in Watt Hall, and at this time he has become a dark gold boss monster that can be attacked by the player. Nirasek can use some spells similar to the universal skills of Necromancers to attack players, including: corpse explosions, teleportation and summoning minions. In addition, Nirasek will also release the druid's skill: Arctic Ice Wind to freeze the player to facilitate the small monsters under his command to cause wanton damage to the player.
In hell difficulty, Nirasek's corpse explosion skill is a killer move for players, because it is so powerful that its damage was weakened in later versions of the game. But if players can withstand the bombardment of Nirasek, the rewards they will receive are also very generous. On the difficulty of hell, Nirasek will drop the key to destruction after his death, and this thing is the key item to unlock the "chaotic events" of the Battlenet.
cause of betrayal
The main reason for Nirasek's betrayal is generally believed to be closely related to the huge pressure he has been under.As the last tribal elder who survived the world, Nirasek has always been carrying the heavy mission of protecting Harrogas. After witnessing Barr and his army of destruction destroying the barbarians one by one, Nirasek couldn't help but completely lose his determination to protect the world's stone.

On the way to find Nirasek
In the grief of the impending failure of the mission, Nirasek couldn't help but think about his promise to protect Harrogas when he was with other elders, so he secretly reached an agreement with Barr to seek Harrogas's safety at the cost of giving up the World Stone. But what Nirasek never expected was that what the demons are best at is breaking the agreement. So Nirasek lived in Harrogas with endless guilt. After the incident was revealed, he fell completely into madness and finally ended his frustrated life under the beating of a group of heroes.
Game settings
In the game, Nirasek's most feared by players is nothing more than his two ace skills: corpse explosion and Arctic ice wind. After the player kills the monster summoned by Nirasek, he is not prevented from using the corpse explosion to seriously injure the player. He can use the corpse before Nirasek detonates the corpse. For example, the paladin can use the redemption skills, the barbarians can release the skill of finding potions, and the necromancer will directly resurrect the corpse or summon the skeleton. Of course, players can also equip the equipment with the affix of "Death Monster Rest" (for example: "Nature's Peace" Dark Gold Ring) to solve the headache of corpse explosion problem.

large number of monsters in front of Nirasek's residence
Under normal difficulty or nightmare difficulty, mages or other characters can directly kill these monsters by using the freezing attribute attacks to prevent them from leaving corpses for Nirasek's use after death. Similarly, bringing some equipment that has the effect of flame resistance or reducing/blocking physical damage can also effectively reduce the killing effect of corpse explosions.
When players fight against Nirasek, they must pay attention to keeping a certain distance from him. Because if the player and the monster are far away from Nirasek, he will be subject to the casting range and cannot use the corpse explosion to deal with the player. Therefore, players can lure the monsters to a farther position and slowly solve them. Assuming that the player is very close to Nirasek, not only will the explosion of the corpse pose a threat to the player, Nirasek will also cast Arctic Ice Wind on the player to freeze the player to give him more output opportunities. Players can carry some thawing potion or some cold-resistant equipment to reduce the negative persistence of the skill.
