Yakamaru is the second boss of the Liberation of Mazcab raid. Yakamaru can be looted once every 2 days for rewards including the superior versions of Teralith, Primeval and Tempest equipment. This boss can only be fought after killing the first boss of the instance, Beastmaster Durzag, at least once. Yakamaru spawns jellyfish and different variations of jellyfish: Durable, Magical, Piercing, Reflecting Jellyfish and Meleefish. It also has a phase where it creates four copies of itself.

According to the fifth stone fragment, Yakamaru was once a spiritual guardian that helped to protect the inhabitants of Mazcab, but fell victim to the corrupting mind magic of the airut shaman, and is now bound to serve them for a more destructive purpose.[1][2] Yakaminu states that Yakamaru takes on the form of a river snake.

Killing Yakamaru for the first time grants 500 reputation with the goebies. Obtaining all unique drops from Durzag and Yakamaru will unlock the title, [Name] the Liberator.

Rewards[edit | edit source]

When Yakamaru is killed, its helmet remains and acts as a reward coffer to collect the drops. Yakamaru has several drop tables that are rolled on to constitute the loot. The consumable table is always rolled, summoning charms are commonly received, and tertiary drops may be received. If the unique drops table rolls either a Mazcab ability codex or piece of achto equipment, the main drop will not be received. If the unique drops table rolls Teci, the main drop table will be rolled multiple times.

Marks of War: 600

Consumables[edit | edit source]

Tertiary[edit | edit source]

Unique drops[edit | edit source]

Yakamaru can only drop one item from this table. If no armour piece or Mazcab ability codex is dropped, the player will receive teci.

The drop rate of any piece of Achto Primeval, Tempest, or Teralith equipment is doubled if the respective non-achto equipment piece is purchased from the Goebie Armoursmith.[3] For example, buying the Teralith Helm will double the chance of getting the Achto Teralith Helm.

A player that owns all fifteen pieces of achto equipment may continue to receive achto armour as drops with the following changes to drop mechanics:

  • Achto armour doubles the chance of receiving a duplicate of that item. In other words, owning the Achto Teralith Helm will double the chance of getting another Achto Teralith Helm, and owning the non-achto Teralith Helm is no longer beneficial.
  • The drop order is no longer enforced. For example, it is possible to receive a second Achto Teralith Helm, followed by a second Achto Teralith Platebody.

Otherwise, armour is gained from Yakamaru in the following order: gloves, boots, helmet, legs, and body.[4]

Progressing in the drop order requires collecting all three of the previous equipment slot's achto equipment - so in order to receive an Achto Primeval robe top, they would have to get all Achto Tempest, Primeval and Teralith gloves, boots, helm and legs. The Achto equipment gained from each equipment slot is based on the combat style the player dealt the most damage with during the kill they obtained that armour; if the equipment piece corresponding to the used style is not owned, that is always gotten before the others, and otherwise there are equal odds of obtaining armour corresponding to one of the unused styles.[m 1]

When killed in the wilderness with achto armour, it will drop a specified amount of coins if you die.

Over many centuries the seeping anima formed constructs; spirit guardians that roams this world's forests and plains. While not sentient, these guardians still strive to conserve the natural order of Mazcab. Affording their own protection to those that may not be able to protect themselves."

When Tuska came she brought with her the Airut that plague this land... The Shaman in particular wields a dreadful magic, spreading corruption where he walks and warping the minds of his victims. The spirit guardian Yakamaru fell prey to this evil. No longer does it protect the inhabitants of this world but instead, like so many others, it must serve its Airut masters."
