Walkthrough
There are two parts to this mission: in the first part, the party is expected to beat 3 Luxon teams, thus earning the right to wield the Spear of Archemorus. In the later part, the party is to use the spear to defeat the mighty kraken named Zhu Hanuku.

Part 1
The two bosses that are with every team have a Resurrection Signet each, which they will use instantly when one of their team members dies.

The first team will come from the left, it will be a led by Daeman and Seaguard Eli. The biggest threat they pose is the interruption they can inflict. Daeman has Choking Gas and can shut down a spell caster completely for some time.

The next team will come from the middle and will feature Aurora and Seaguard Gita. Seaguard Gita is a monk so it's best to dispatch her quickly. Beware Aurora's Barrage skill as it deals Area of Effect damage. Also, the two Luxon Warriors of this team can be a problem if they gang up on a spellcaster.

The third team is Argo's team and he can be quite formidable for the unaware. His elementalist attacks and especially his special skill Argo's Cry can easily overwhelm the party if they are not prepared. The other boss, Seaguard Hala, is a mesmer but offers minimal threat. The party should focus its attack on Argo from the very beginning and make sure to interrupt his cry.

After the three teams are defeated, a cutscene will lead to the next part.

Part 2
To make the kraken Zhu Hanuku appear on the map, you must first kill a specific group of Kraken Spawn that patrol along the edge of the Jade Sea. Exit the arena through the gate that opened after the Part 1 cutscene (opposite the spear pedestal). You will be walking out onto the Jade Sea. There will be groups of Naga and Rot Wallows on the shore. Once you get to the sea, you will encounter groups of Creeping Carp and the like, but you will also notice groups of Kraken Spawn. Destroy these and a new Kraken Spawn will appear that will head to a destination further east. Kill this seconds group of Kraken Spawn to make Zhu Hanuku appear.

The kraken Zhu Hanuku has only two skills: Resurrect which enables him to resurrect the recently slain spawn and a very devastating spell called Jade Fury. Defeating the kraken can be easily achieved if the party keeps him interrupted to shut down the monster's lone offensive skill, Jade Fury. If this skill is denied, killing the monster will be noticeably easier.

One Necromancer with Spinal Shivers/Shivers of Dread and a Wailing Wand can keep the kraken interrupted permanently. Warriors and Assassins can also bring an interrupt, such as Distracting Blow and Disrupting Stab. Ritualists can bring Dissonance and cast it near the kraken. A Ranger can use Broad Head Arrow (it can be captured from Daeman earlier in the mission) to keep Zhu Hanuku constantly dazed as long as he has enough Expertise to keep meeting the energy cost. Concussion Shot could provide a non-elite alternative, if the player felt that he could interrupt one of the kraken's skills(since Jade Fury takes 3 seconds to activate, this shouldn't be a challenge). Alternatively, he can simply bring Distracting Shot and Savage Shot, and just alternate them. As both the Kraken's skills have a fairly long cast time and cooldown, this should be easy to do. An Assassin with Beguiling Haze can also help to keep Zhu Hanuku dazed. If you do not have several interrupters, it is advisable to not interrupt his Resurrect. Instead, after he resurrects the Kraken Spawn kill them to charge the spear.

Zhu Hanuku still has a very high health and armor level, as well as a quite potent ranged attack. The damage dealt by the Spear of Archemorus is multiplied several times against him, though, so it is highly recommended to enter this battle with the spear fully charged. On a level 5 charge, the spear can deal up to 1900 damage when used against the kraken.

Animal Charming Exploit
It is possible to exploit a pair of bugs in this mission to capture a level 20 elder crab without any hassle. This behavior will likely be fixed by ArenaNet, but in the interim, it still works.

When the mission starts, go through the gate but do not descend into the arena. Instead, hug the left wall and go across the bridge to where Daeman's team is. Surprisingly, this will not trigger the doors and they will stay inside their gate. This is the first bug. They will only come out if someone goes down into where the game keeps pinging.

Once there, the two crabs for the Luxon Rangers in Daeman's team will be by the gate, while the rest of the team will be further away. Even though the crabs technically belong to those rangers, a player can come adjacent to the crab and use Charm Animal on it to make it his. This is the second bug. Together, the two bugs allow a player to capture a level 20 elder pet in under 1 minute.
