Overview: Scurrius, the Rat King, is a mid-level boss in Old School RuneScape located in the Varrock Sewers.

The boss fight involves three distinct phases, each with different mechanics, and offers valuable rewards such as the Twinflame Staff, Giantsoul Amulet, and Scurrius' Spine for crafting Rat Bone Weaponry.

Recommended Gear

Since Scurrius is a mid-level boss, you'll want to bring mid-tier armor and weapons. Here are some suggestions:

Armor:

Rune Armor, Green D'hide, or Mystic Robes for combat levels between 70 and 100.

Barrows Armor, Black D'hide, or Void Equipment for higher-level players or solo attempts.

Weapons:

Dragon Scimitar, Magic Shortbow, Iban's Staff, or better if you have 80+ combat stats.

Consider using Rat Bone Weapons (Bone Mace, Bone Staff, Bone Shortbow) if you get Scurrius' Spine drop, as they give bonus damage against rats.

Inventory:

Super Combat Potion or Ranging Potion.

Prayer Potions.

Monkfish or better for healing.

Teleport Tab for quick exits.

Where to Find Scurrius

Location: Scurrius can be found in a small section of the Varrock Sewers, just east of Varrock Castle.

Entrance: Use the manhole in the sewer and run west to find Historian Aldo, who is located just outside of Scurrius' lair. You can choose to do a public fight or an instance.

How to Defeat Scurrius

Scurries go through three phases, each with different mechanics and attack styles. Here's how to tackle each phase:

Phase 1: 100% to 75% Health

Attack Styles: Scurrius uses melee, magic (blue lightning), and ranged (green cloud darts).

Protection: Use Protect from Melee most often, as its melee attack is the most damaging. Switch protection prayers if necessary.

Phase Transition: When Scurrius reaches 75% health, it will eat from one of the three food piles in the lair and only attack with magic and range for 10 seconds.

Rubble Attack: Watch out for falling rubble-move out of the way when shadows and debris appear to avoid damage.

Phase 2: 75% to 25% Health

Healing Mechanic: Scurrius will heal by eating from the food piles, restoring up to 5 times during this phase.

Giant Rats: If you're struggling with damage, consider killing the Giant Rats that spawn with Scurrius. They'll respawn after the second and third phases.

Focus on DPS: Continue applying damage and keeping Scurrius from healing too much.

Phase 3: 25% to 0% Health

Rubble & Damage: Rubble continues to fall, and Scurrius attacks all players while staying in the center of the lair.

Stay Mobile: Keep moving to avoid falling rubble while focusing all your DPS to finish the fight.

Defeat: Once Scurrius is dead, its loot will drop, and the fight will reset in about 20 seconds.

What Loot Does Scurrius Drop?

Scurries have a variety of drops, including armor, weapons, runes, and combat supplies. The unique drop is Scurrius' Spine, which can be used to create Rat Bone Weaponry.

Scurrius' Spine (Untradeable)

Alternatively, you can pay 50,000 GP to Historian Aldo outside Scurrius's lair to craft the Rat Bone Weapon for you.
