Locating The Rat King Scurrius


Navigating the depths of the Varrock sewers to face the formidable Rat King, Scurrius, is an adventure reminiscent of unraveling a medieval legend hidden beneath the bustling city. The journey to Scurrius’ lair is a testament to the courage and determination required to confront such a creature, lurking in the shadows of Varrock’s underbelly.

Accessing Varrock Sewers

The entrance to the Varrock sewers, a network of grim corridors beneath the city, lies tantalizingly close to the grandeur of Varrock Castle. Picture yourself stepping off the cobblestone streets, filled with the hustle and bustle of city life, and descending into the dimly lit entrance of the sewers. This manhole, a gateway to the unknown, is located just to the east of Varrock Castle, serving as the first step in your quest to confront Scurrius.

As you navigate through the sewers, the ambiance shifts. The light fades, and the air becomes thick with anticipation. The path is not for the faint-hearted, with echoes of dripping water and the distant scurrying of unseen creatures accompanying you. Yet, this is where bravery shines brightest, guiding adventurers through the darkness.

Once within the sewers’ embrace, the journey to Scurrius’ lair is akin to navigating an ancient labyrinth. Heading east from the entrance, adventurers must traverse the serpentine passageways, each turn taking them deeper into the bowels of the city. It’s a path less traveled, where the air grows denser, and the shadows seem to whisper secrets of the past.


Combat Strategies for Battling Scurrius


The confrontation with Scurrius, the Rat King, in the depths of the Varrock sewers, is a battle that requires not only strength and gear but also a keen understanding of combat strategies. These strategies form the backbone of a successful engagement, ensuring that adventurers can navigate the complexities of the fight with confidence and skill.

Initial Engagement

The initial engagement with Scurrius is a crucial phase that sets the tone for the entire battle. Upon entering the lair, it’s paramount to activate the correct protection prayer—Protect from Melee—due to Scurrius’s initial preference for close-quarters combat. This early decision helps mitigate the damage from his formidable tail strikes, allowing adventurers to focus on delivering their own offensive maneuvers.

Protection Prayers

As the battle progresses, Scurrius demonstrates his mastery over all three combat styles, necessitating a dynamic approach to protection prayers. Switching between Protect from Magic and Protect from Missiles is essential when Scurrius employs his range and magic attacks. These switches are critical during the fight, especially when responding to the distinct visual cues of Scurrius’s ranged and magical onslaughts.

Positioning and Movement

Strategic positioning and movement are vital to avoid Scurrius’s attacks and environmental hazards. When Scurrius summons debris from the ceiling, observe the shadows on the ground to anticipate where the hazards will fall. Swiftly moving out of these marked areas can prevent unnecessary damage and maintain the adventurer’s health for the duration of the fight.

Phase Transitions

Understanding Scurrius’s phase transitions is key to maintaining control of the battle. As Scurrius transitions to his healing phase, by consuming cheese found within his lair, the strategy shifts. It becomes imperative to balance offense with the need to interrupt or outpace his healing, ensuring that the battle does not prolong unnecessarily.

Responding to Scurrius’s Healing Phase

The healing phase presents a unique challenge, as Scurrius attempts to replenish his health. To counteract this, adventurers must increase their offensive pressure, utilizing high-damage abilities and special attacks to overcome the healing and push Scurrius towards the next phase of the fight.

Avoiding Debris and Environmental Hazards

Environmental awareness is crucial throughout the encounter. In addition to moving away from falling debris, adventurers must be mindful of other environmental hazards that Scurrius may employ. Quick reflexes and an acute awareness of the surroundings are indispensable tools in navigating these challenges successfully.


Special Attacks and Countermeasures


Identifying and Reacting to Magic and Range Attacks

  • Magic Attacks: Scurrius will signal his magic attacks with a distinctive animation, often involving a blue glow or projectile. Players should switch to Protect from Magic to mitigate these attacks.
  • Range Attacks: Similarly, range attacks are telegraphed by Scurrius through a different animation, possibly involving green projectiles. Switching to Protect from Range is crucial to minimize damage.

Dealing with Minion Spawns

  • Rat Minions: Throughout the battle, Scurrius will summon rat minions. These can be swiftly dealt with by using area-of-effect (AoE) weapons or spells. For melee users, items like the Halberd can be effective; for rangers, chinchompas; and for mages, spells like Ice Barrage. Utilizing the bone weapons crafted from Scurrius’s spine provides an instant kill capability on these minions.

Optimizing DPS Against Healing

  • Interrupting Healing: Scurrius attempts to heal by eating from cheese piles located in his lair. To counteract this, players must maximize their damage per second (DPS) during this phase. This can be achieved by pre-loading powerful special attacks, optimizing gear for maximum DPS output, and utilizing combat potions to boost attack stats. Magic users might find casting vulnerability spells to increase damage taken by Scurrius effective, while melee and range users should consider their most potent special attacks or rapid-fire capabilities.

Avoiding Debris and Environmental Hazards

  • Debris: Periodically, Scurrius will cause debris to fall from the ceiling. Players should watch for shadows on the ground, indicating where debris will land, and move away accordingly to avoid damage.
  • Environmental Hazards: Apart from debris, Scurrius’s lair might have other environmental hazards, such as areas that could restrict movement or areas that enhance Scurrius’s abilities. Maintaining situational awareness and staying mobile can mitigate these risks.

Collecting Loot


Collecting loot from Scurrius, the Rat King, is straightforward, with players advised to pick up valuable drops such as Rune items, which are prevalent and serve as primary drops from the boss. These items are highly recommended for High-Level Alchemy due to their value. Additionally, the boss drops coins in quantities ranging from 1,000 to 9,000, along with various food items, prayer potions, and combat-related potions which can aid in extending the duration of each trip. The boss room’s design allows for easy collection of loot, especially in private instances where players can collect all their loot at the end of their trip without interference from other players.

Healing and Resetting for Subsequent Battles

Healing and resetting for subsequent battles with Scurrius emphasize the use of the boss’s environment and mechanics for sustainability. The boss room contains cheese piles that players can eat to heal themselves completely, though this can only be used when not in combat and has a cooldown of 10 minutes, similar to the altars in God Wars Dungeon boss rooms. Furthermore, the Amulet of Blood Fury is highlighted as an effective item for passive healing, especially since Scurrius and its minions’ attacks can be fully negated with the correct prayer, allowing for minimal damage taken and thus longer trips without the need for extensive healing.


Unique Drops and Rewards


Scurrius Spine and Bone Weapons

The Scurrius Spine is a notable drop from Scurrius, with a drop rate of 1 in 33. This spine is a key component in crafting unique Bone Weapons tailored for combating rats, including the Bone Mace, Bone Bow, and Bone Staff. These weapons are especially effective within the Scurrius encounter, providing significant advantages such as the ability to quickly eliminate spawned rat minions and enhanced damage against the Rat King himself. The crafting of these weapons requires the spine along with a Rune Mace for the Bone Mace, a Yew Shortbow for the Bone Bow, and a Battlestaff for the Bone Staff, making them accessible yet potent tools for players engaging with this boss.

Pet and Other Notable Drops

The Scurrius pet, a sought-after cosmetic drop, represents the boss in miniature form, with a drop chance of 1 in 3,000, making it a rare but prestigious reward for dedicated players. Beyond the pet, Scurrius offers a variety of other drops that contribute to its appeal as a farming target for mid-level players. These include high-alch value items, essential resources for skill leveling, and consumables that can aid in further bossing activities. The unique drops and rewards from Scurrius cater to a range of player interests, from those seeking to enhance their combat efficiency with specialized weapons to collectors aiming for rare cosmetic pets.
