Scurrius is the rat boss reached through the Sarim Hub's Scurrius destination. This sends you to the sewer entrance rather than starting the fight immediately. The encounter combines a tail swipe, ranged and magic projectiles, summoned rats and falling rubble. His base 1,100 Hitpoints make sustained damage and correct protection prayers useful throughout the fight.
Getting there
Choose Scurrius in the teleport Hub, then use the entrance's private option and confirm creation of the instance. This entrance route skips the instance-token charge. The public option currently directs players to use private entry.
Instance creation respects teleport restrictions and blocks creation from Wilderness locations outside its allowed exception. Hub travel also uses the usual teleport checks, including teleblock, locked states and the level-20 Wilderness departure limit. Use the exit's cross option for a confirmation, or quick-escape to return to the sewer entrance.
Fighting Scurrius
Scurrius begins with melee tail swipes. His first health transition is below 80%, when he moves toward a food trough. During the trough sequence he continues to launch magic or ranged projectiles and can heal. The healing amount scales with the number of nearby players, so this is a useful time to keep attacking rather than treating his movement as a complete pause.
Below 31% health, the low-health phase uses ranged and magic attacks with occasional falling rubble. The fight reevaluates its phase from current health, so healing can move it back toward an earlier phase. Watch the attack itself instead of assuming that a health threshold permanently locks a phase.
Protection prayers reduce the boss's scripted base damage ranges rather than eliminating every attack. Tail swipes roll up to 55 without protection, or 9 with Protect from Melee. Magic rolls up to 55, or 5 with Protect from Magic; ranged rolls up to 55, or 7 with Protect from Missiles. These are base rolls before additional player damage modifiers.
Move away from marked rubble tiles: after a two-tick delay, players still on an affected tile face a base hit of 18–25. A rubble sequence marks ten positions, including the targeted player's current position. Summoned rats arrive in groups of six; their damage listener allows a normal incoming hit to remove their remaining health. Deal with them while continuing to watch projectiles and rubble.
Rewards
Scurrius' spine is a notable reward. The sewer trader exchanges one spine for one antique lamp after confirmation. Scurry is associated with a separate pet-unlock roll.
Main drop table
The table lists the ordinary boss's configured main loot and quantity per awarded outcome, before player effects. Guaranteed entries are separate from optional rewards. It excludes shared bonus cash, clue, rare-table and event rewards. Rates are omitted because candidate selection, priority and player modifiers affect the final chance.
