By Jesus Marquez | Created: November 08, 2024 | Last updated: July 11, 2025 | Read Time: 9 minutes

This is the end! Well, at least the end of The First Necromancer quest series. Welcome back. We are so glad you are coming back and following each of the guides for this moment. Rasial, The First Necromancer, is waiting for you to defy him and save the City of Um bravely. Alpha vs Omega RS3 quest is all about this epic fight between you and Rasial; are you prepared for the battle of your life? Let’s protect the City of Um and end Rasial’s plan for good. So, let’s begin!

Alpha vs Omega RS3 Requirements

This is the seventh quest in the line of The First Necromancer quest series, and one thing about RS3 Alpha vs Omega is that it is only for members. Moreover, you can expect to spend around 20 to 30 minutes completing this fight against Rasial, so free the space to concentrate and deal with him. You can check the requirements to complete your mission here successfully:

  • Completion of Remains of the Necrolord
  • 95 Necromancy
  • T70+ Necromancy Combat Equipment
  • Salve Amulet (e)
  • Best Combat Summoning Familiar you’ve available
  • Best God Book you have

RS3 Walkthrough Alpha vs Omega

Before you can begin with the quest, you must return to the City of Um, but this time with a little twist since you must talk to Rasial, the First Necromancer, instead of Death. You will find him on the bridge of the City of Um. When you get close to him, Rasial will tell you he is finally ready to face you in his citadel.

After his invitation, you must talk to Kharen on the docks to travel to Rasial’s Citadel. Be cautious in this section because you won’t make any progress in the Alpha vs Omega RS3 quest by using the ‘Travel’ option on Kharen or using the boss portal in War’s Retreat or Boss Portal in Max Guild.

Hermod, the Spirit of War

At this phase of the Alpha vs Omega RS3 quest, you must prepare for high-level combat. Before you talk with Kharen, we recommend banking all the items you don’t want to lose since this is a dangerous quest. Rasial is immune to poison damage but not to stuns; however, you can use different Action Bats with Touch of Death, Soul Sap, and Necromancy Basic Attacks on it to access them while moving and attacking. Before facing Hermod, remember to have Darkness active to take around 20% less damage during the battle.

Once you embark and reach the Citadel, Rasiel will immediately call Hermod, the Spirit of War, and allies (2 Putrid Zombies and 4 Skeleton Warriors) to attack you. The fight against Hermod will be in the same way you remember in the Spirit of War quest; you will only be able to defeat him using Necromancy. You won’t need to defeat the Allies to continue with the next phase of the RS3 Alpha vs Omega quest.

Rasial, The First Necromancer

When you finish your fight with Hermod, Rasial will attack you immediately. You will find the story mode version is weaker than the one you will fight post-quest; still, he has the same mechanics, so don’t underestimate him for this slight decrease in power. You won’t be able to kill him using a Deathtouched Dart, and the only way to fight him is using Necromancy.

If you need to leave for any reason, you don’t need to worry about defeating Hermod again, and you will start the fight against Rasial when he attacks you. You can restock if required in these sections of the Alpha vs Omega RS3 quest. This battle against Rasial will take you into four different phases, and in each of them, he will obtain new attacks as the fight progresses.

Phase 1

When you begin with Phase 1, Rasial will have access to a wide variety of abilities to use against you during your fight during the Alpha vs Omega RS3 quest:

  • Death Spark – Rasial will use an Omni Guard, and with every auto-attack he makes will give him one stack of Death Spark. When he reaches 6 stacks, the following auto-attack will increase damage, and if you are not lucky enough to be stun immune, it will turn off any overhead protection prayer/curse you activated. You can check this underneath the main health bar.
  • Dive – if you are in a range of two tiles from Rasial, he will yell at you ‘Hahahahaha. Nowhere near.’ and then will dive to a random location in the arena far from you. Be cautious since this action will cause him to follow up with some conjures.
  • Touch of Death — This ability deals moderate damage and adds two Necrosis Stacks to Rasial when it reaches you.
  • Finger of Death – Rasial will use this ability to deal high damage on you, and if he uses any Necrosis Stacks, he will tell you, ‘Suffer at my hand!’ as an indicator of this.
  • Soul Sap – Rasial will grant one stack of Residual Soul on him when he uses this ability on you.
  • Volley of Souls – When Rasial wields a Soulbound Lantern and has five stacks of Residual Soul, he will use Volley of Souls, yelling, ‘This is true power!’
  • Spectral Scythe – when you are within two tiles of Rasial, he will yell and use the level 1 Spectral Scythe ability. However, this is not common since Rasial prefers to dive instead of using Scythe.
  • Shadow Step – Rasial will barge towards your position, inflicting you a 3 seconds stun and bind if you’re not stun immune. Beware because he will follow up with Spectral Scythe if he uses this ability.
  • Undead Conjures – Rasial will yell, ‘Rise, my minions!’ and immediately will summon two Skeleton Warriors, which have 3,900 HP and will attack you with melee. During phase 3, he will add a Putrid zombie, which will have 3,900 health and inflict poison damage on them. These will continue until you kill Rasial or phase 4 begins. If Rasial dives away, he will always follow up with conjures.

Phase 2

You will reach this phase when Rasial has 350,000 HP, and you will know the beginning because he will yell, ‘You've come a long way, but clearly not far enough’. Moreover, he will summon two Soul Obelisk with 6,000 HP each and will periodically charge up. These Obelisks will give Rasial a stack of Residual Soul, and when it’s filled, they will let him cast Volley of Souls more frequently. To go through this stage of Alpha vs Omega RS3, we recommend you don’t waste your destroying them because they will return after you do so.

Phase 3

This phase will begin when Rasial reaches 200,000 HP. He will add his Spirit Wall ability to the list. You will know when you enter this phase because he will taunt ‘Join us… in death!’ and summon a wall of seven spirits to tiles behind you. This will force you to move forward and will damage you if you are in contact with it.

You can easily avoid the wall by walking two tiles behind and allowing the minimal movement possible while avoiding this ability. You can make this recommendation easily since the hitbox will appear late after the animation. However, beware because Rasial can use this mechanic twice and can make your way to completing this tip. Still, if this happens to you, you can take another two steps backward toward the second Wall of Spirits.

During this phase of Alpha vs Omega RS3, Rasial can use Dive to reposition after using the wall. Moreover, he will conjure enhanced attacks, adding a Putrid Zombie into this chaotic mix.

Phase 4

Entering the next phase of the RS3 Alpha vs Omega quest is fascinating. When Rasial reaches 100,000 HP, he will yell, ‘Ha! No more games!’ letting you know you are in the final part of your fight with him. You will be teleported to the upper floor at the back of the citadel; you will be immobile and stun-immune during this process. However, in this phase, Rasial won’t perform any attacks from previous phases, and he will only use auto-attacks that are imbued with Death Spark.

Although Rasial will perform the animation using Finger of Death, he will only launch auto-attacks, making it the first source of damage in this phase. Be cautious where you run over since shadows will appear on the ground that indicate Necrotic Explosions, which will deal you 2,500 damage if you are in the AoE. One of these shadows will always be targeting the tile you are in when Rasial uses his attacks. These shadows have a 1x1 AoE, and you can avoid them easily; still, you must avoid running erratically since this only attack can kill you.

However, you will enter the final phase when you dumb Rasial’s hit points down to 30,000 or less. You can use all damaging attacks to accomplish these and finally defeat him and finish the Alpha vs Omega RS3 quest.

The End Of Rasial, The First Necromancer

Once Rasial’s health reaches 0 HP, his physical form will be destroyed, and he will now turn into a giant head. He will allude to Gielinor and the universe as a whole being who is in danger from “The Shadows” and will reveal part of his motivation to make you his apprentice since he was testing you. At this stage of the RS3 Alpha vs Omega quest, Rasial will release all the souls in his services before disappearing to be able to rebuild his physical body.

After this event, you must head and talk to Death in the City of Um, and he will teach you more about Rasial and help you complete this quest.
