Yakamaru

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. Yakamaru spawns jellyfish and different variations of jellyfish: Durable, Magical, Piercing, Reflecting Jellyfish and Meleefish. It also has a phase where it creates 4 versions 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.

Killing Yakamaru for the first time grants 500 reputation with the goebies.

Rewards
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.

Tertiary
Only one burial charm may drop at a time. The burial charm table and effigy table are not linked - a player may receive drops from one, both, or neither.

Unique Drops
Yakamaru can only drop one item from this table. If no armour piece 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. 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 > Helm > Legs > Body

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 first 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.

Yakamaru's gloves drop chance is higher than Durzag's.
