Recommended Gear for Cerberus

Cerberus primarily uses melee attacks and summons ghosts that deal melee, magic, and ranged damage. Protection prayers and defensive gear are crucial for efficiently surviving the encounter.
Melee Setup (Recommended for Most Players):
Using melee is the most effective combat style for Cerberus. Strong weapons such as the Abyssal Whip, Osmumten's Fang, or Ghrazi Rapier are ideal. These should be paired with defensive and prayer-boosting gear.
Suggested items include:
Helmet: Serpentine Helm, Neitiznot Faceguard, or Helm of Neitiznot
Body: Karil’s Leathertop or Bandos Chestplate
Legs: Karil’s Leatherskirt or Bandos Tassets
Boots: Primordial or Dragon Boots
Cape: Fire Cape, Infernal Cape, or Ardougne Cloak
Amulet: Amulet of Torture or Amulet of Fury
Ring: Berserker Ring (i) for offense, or Ring of Suffering for defense
Inventory Tips:
Multiple prayer potions to maintain protection prayers
A Super Combat or Divine Super Combat Potion to boost melee stats
A few pieces of food or Saradomin Brews for recovery
A teleport method in case a quick escape is needed
This setup balances offense with magic defense and prayer efficiency, which helps sustain longer trips and minimize resource usage.

Mastering Ghost Prayer Timing

A crucial aspect of the Cerberus fight is switching protection prayers at the right time during the ghost phase. Each summoned ghost deals damage from a specific combat style: melee, magic, or ranged. Without the correct prayer active, players can lose up to 30 prayer points per hit.
The most reliable method is to watch the prayer orb. When the orb drops by approximately 30 points, it signals that it is time to switch to the next protection prayer in the ghost sequence. This approach eliminates guesswork and reduces the risk of misclicks or panic during the fight.
Dodging Lava Pools Effectively
Cerberus begins using lava pools when her health drops below 200. These pools spawn around the player’s current position shortly after the ghosts appear, often creating a deadly combination of mechanics.
To avoid the lava damage, run to the opposite side of the room immediately after the ghosts are summoned. Make sure to activate the correct prayer for the first ghost before moving. This sequence allows players to dodge lava while maintaining protection from the incoming ghost attacks.
Why Ghost Skipping and Red X Flinching Are Inefficient
Techniques like ghost skipping and red X flinching are sometimes used to conserve prayer potions, particularly by Ironman accounts. However, these methods slow the fight significantly and reduce overall kills per hour.
Focusing on standard kill strategies with proper prayer timing and movement is much more efficient. Slayer experience gains remain consistent, and the saved time can be used to gather resources through skilling. Farming and thieving, for example, can help generate prayer potion ingredients and additional gold to maintain supplies.

FAQs About Cerberus
Q: How do you know when to switch prayers for the ghosts?
A: Monitor the prayer orb closely. When it drops by about 30 prayer points, switch to the next protection prayer in the ghost rotation. This visual cue is more reliable than watching the ghost animations.
Q: How can the lava pool attack be avoided?
A: As soon as the ghosts are summoned, activate the correct protection prayer and run to the far side of the room. Lava pools appear beneath the player’s current location, so immediate movement avoids the damage.
Q: Are ghost skipping or red X flinching effective?
A: These techniques are not recommended for most players. While they reduce potion usage, they also lower kill speed and make Slayer tasks take much longer.
Q: What is the order of the ghost attacks?
A: The ghosts appear in a fixed left-to-right order: red (melee), blue (magic), and green (ranged). Memorizing this sequence ensures accurate and timely prayer switches.
Q: How can Ironman accounts manage potion costs?
A: Consistent kills using the prayer orb method minimize waste. Players can also support potion supplies through farming Ranarrs and gathering secondaries via thieving or other skilling methods.
Final Thoughts
Cerberus is a demanding boss who rewards precision, awareness, and preparation. Players who focus on proper prayer switching, efficient gear setups, and smart movement will find the fight more manageable and significantly more efficient.
Instead of relying on slow or complicated tactics, focusing on consistency and timing offers stronger results in the long run. Whether the goal is pet hunting, high-value drops, or Slayer progression, mastering Cerberus through these fundamentals leads to lasting success.
