In this comprehensive guide, we will dive into the depths and explore everything you need to know to conquer Yakamaru and reap the rewards it offers.

Understanding Yakamaru

Before we delve into the strategies and tactics for defeating Yakamaru, let's get to know this formidable boss a bit better:

  1. Location: Yakamaru is located in the Liberation of Mazcab raid, accessible after completing the quest "Call of the Ancestors."

  2. Mechanics: Yakamaru boasts a complex set of mechanics and phases that require coordination and teamwork among raid members. These mechanics include poison pools, tentacles, drowning, sand pits, and more.

  3. Rewards: Defeating Yakamaru can yield some of the most coveted rewards in RS3, including unique abilities, combat pets, and Teci, which can be exchanged for high-level gear and cosmetic items.

  4. Roles: During the fight, raid members are typically assigned specific roles, such as base tank, chargers, and north/south stunners. Understanding and executing these roles is crucial for success.

Preparation and Gear

Before facing Yakamaru, you'll need to prepare both mentally and in terms of your gear and inventory. Here are some key considerations:

  1. Gear: Optimal gear setups for fighting Yakamaru generally include high-level armor, weapons, and jewelry. Superior Elite Void Knight gear is commonly used for its damage bonus. Augmented weapons with appropriate perks can also significantly enhance your performance.

  2. Inventory: Bring a variety of supplies, including food (sharks or better), prayer potions, and Saradomin brews for emergency healing. Additionally, consider using stat-boosting potions like Overloads or Supreme Overloads to maximize your combat stats.

  3. Abilities: Set up your ability bar with a combination of damage-dealing abilities, defensive abilities, and utility abilities. Ensure you have access to stuns, bleeds, and area-of-effect abilities.

  4. Yakamaru Abilities: Familiarize yourself with Yakamaru's abilities and phases, as this knowledge is critical for avoiding lethal attacks and executing mechanics correctly.

Strategies for Success

Now, let's delve into the strategies that will help your team conquer Yakamaru:

  1. Roles and Responsibilities: Before the fight begins, make sure everyone in your raid team understands their assigned roles and responsibilities. Communication is key, so use voice chat or text chat to coordinate effectively.

  2. Phase 1: Poison Pools: In this phase, your goal is to lure Yakamaru to the poison pools, which deal significant damage to it. Have your base tank provoke Yakamaru, and make sure DPS players focus on the poison pool.

  3. Phase 2: Sand Pits: During this phase, players must stand on sand pits to prevent Yakamaru from healing. Coordinate with your team to ensure that enough players are on the sand pits at all times. Avoid standing on a sand pit when the bar fills to prevent drowning.

  4. Phase 3: Freeing North and South Clans: In this phase, you will need to free the north and south clans from their respective cages. A stun rotation is typically used here to keep the minions under control. Make sure your stunners are ready and in position.

  5. Phase 4: Sharks and Tendril Tentacles: During this phase, Yakamaru spawns Tendril Tentacles that must be killed before they reach a player and kill them. Ensure that your DPS players focus on these tentacles while maintaining their assigned roles.

  6. Phase 5: Jellyfish and Lightning: This phase introduces Jellyfish and Lightning orbs. The key is to avoid the Jellyfish, which can stun you, and stay away from the Lightning orbs, which can deal massive damage. Follow your team leader's instructions for movement and safety.

  7. Phase 6: Voicemail: In the final phase, your team will face Yakamaru's ultimate attack, Voicemail. Players must protect themselves using the appropriate protection prayers and debuff Yakamaru's defenses. Coordination is crucial to survive this phase.

Tips for Success

To increase your chances of successfully defeating Yakamaru, consider the following tips:

  1. Practice: Joining a learner group or watching video guides can help you become familiar with the mechanics and phases of the fight.

  2. Teamwork: Good communication and teamwork are essential. Be open to feedback and willing to adapt your strategy as needed.

  3. Role Flexibility: In some cases, you may need to be flexible with your assigned role if a teammate is struggling or goes down.

  4. Perseverance: Yakamaru can be challenging, and you may not succeed on your first attempt. Keep practicing and refining your strategy with each attempt.


Defeating Yakamaru in RuneScape 3 is a challenging yet rewarding endeavor that requires teamwork, coordination, and a deep understanding of game mechanics. By preparing adequately, learning the phases and mechanics, and working together with your raid team, you can conquer this formidable boss and claim the valuable rewards it offers. So, gather your fellow adventurers, dive into the depths, and prepare to face the aquatic beast in the Liberation of Mazcab raid. Victory awaits those who dare to challenge Yakamaru!
