Welcome to my Scurrius guide! Scurrius the Rat King is a mid-level boss recently added to the Varrock Sewers in Old School RuneScape. Designed as an introduction to bossing mechanics, Scurrius is perfect for players looking to practice switching prayers, dealing with multiple monsters, and learning to avoid environmental hazards—all while gaining solid XP rates. This guide will cover requirements, gear, inventory setups, travel, combat strategies, and loot for solo players.

Requirements

Scurrius is a members-only boss but requires no quests to unlock, making it accessible to mid-level players.

Combat stats requirements:

· Attack, Strength, Defense: 60 minimum

· Ranged or Magic: 60 recommended if you plan to use them

· Prayer: 43 (for overhead prayers: Protect from Melee, Ranged, Magic)

You don't need maxed stats to fight Scurrius, but higher stats will make the fight faster and more efficient.

Gear Setup

Scurrius has low defense across all combat styles, so most weapons and armor will work. While the fight can be completed using melee, ranged, or magic, melee is often the most cost-effective and straightforward option.

Recommended Melee Gear

· Helm: Torva Helm (best-in-slot), Serpentine Helm, Berserker Helm, or Void Melee Helm if using the full Void set

· Cape: Infernal Cape (best), Fire Cape, God Cloaks for prayer bonus, or Obsidian Cape for defense

· Necklace: Amulet of Torture (best), Amulet of Strength, Fury, or Glory

· Weapon: Scythe of Vitur (best, but expensive), Bone Mace (requires Scurrius Spine), Abyssal Tentacle, Dragon Scimitar, or Rune Scimitar for budget setups

· Shield: Avernic Defender (best), Dragon Defender, Obsidian Shield, Book of War, or Rune Kite Shield

· Body: Torva Platebody (best), Bandos Chestplate, Fighter Torso, Void Knight Top, Obsidian Top

· Legs: Torva Platelegs, Bandos Tassets, Void Knight Legs, Obsidian Legs, or Rune Platelegs

· Gloves: Ferocious Gloves (endgame), Void Knight Gloves, Barrows Gloves, or Combat Bracelet

· Boots: Primordial Boots (best), Dragon Boots, Rune Boots, Climbing Boots

· Ring: Ultor or Bellator Rings (best), Berserker Ring (imbued recommended), Ring of Shadows, Warrior Ring, or Ring of Wealth

Inventory Setup

Essential items to bring:

· Food: Monkfish, Sharks, Swordfish, or Sea Turtles

· Potions: Super Combat Potions (or separate Super Attack, Strength, Defense), Prayer Potions or Super Restores

· Special Attack Weapon: Dragon Dagger, Dragon Claws, Void Waker, Crystal Hird, Godsword, or Sidon

· Miscellaneous: Quick weapons (e.g., darts) for clearing rats, teleport tabs for Varrock

Travel to Scurrius

The boss is located in the Varrock Sewers, near the entrance to Varrock Castle. Travel options:

· Varrock Teleport for the closest route

· Zerker Teleports or running from the Varrock East Bank

You can enter Scurrius in either a public instance (peek to check players) or a private instance (free, solo instance).

Fighting Scurrius

Basic Mechanics

1. Melee Attacks: Scurrius uses a tail slap for melee. Protect from Melee is your default.

2. Environmental Hazards: Rocks drop from the ceiling. Shadows indicate impact zones; step out to avoid damage.

3. Healing Phase (<80% Health): Scurrius eats from food piles, temporarily stopping melee attacks. Rats on his back attack with Magic (blue lightning) and Ranged (green projectiles). Switch prayers accordingly.

4. Rat Spawns: Rats have 15 HP and low damage. Fast weapons or multi-hit attacks (like Bone Mace) clear them efficiently.

5. Enraged Phase (<30% Health): Scurrius stops healing and uses only Magic and Ranged attacks while dropping rocks. No melee attacks occur in this phase.

Tip: Use food piles to fully heal between spawns, but only when all rats are cleared. Piles have a 10-minute cooldown.

Loot

While Scurrius is more focused on teaching mechanics and XP, the boss drops:

· Average Loot: ~9.5k OSRS gold per kill

· Unique Drop: Scurrius Spine (1/33 drop rate) → craft Bone Mace, Bone Bow, or Bone Staff for rat-specific combat

· Pet: Scuri Pet (1/3,000 drop rate)

XP rates are generous, especially for mid-level players, making Scurrius a great spot for practice and progression.

Conclusion

Scurrius the Rat King is an ideal mid-level boss for learning OSRS mechanics, switching prayers, managing multiple enemies, and practicing movement. While the loot isn't game-changing, the XP and unique items like the Bone weapons and rare pet make it worthwhile. Soloing Scurrius is fully achievable with mid-level stats and basic gear, and this guide should help you get started efficiently.

Best of luck to all aspiring bosses, and may your Scurrius kills be swift and rewarding!
