Zos Shivros Channel (mission)

Challenge Mission. Protect Battle Priest Calibos for as long as you can. Killing a Luxon Adept in the surrounding area gives a morale boost, a score bonus and the blessing Rage of the Sea. New "waves" of more powerful enemies will be announced and a short timer will appear. A Hold-out score bonus is given every minute. At regular intervals the score values increase.

For setting the overall high score, you receive 8000 Luxon faction and 2000 gold. You will receive a much lower percentage of that for not setting any high score.

Waves
The first wave will be composed of Outcast Deathhands, Outcast Ritualists, Outcast Warriors and Outcast Assassins.

The second wave will be composed of Naga Ritualists, Naga Warriors and Naga Archers.

The third wave is made up of Leviathan Claws, Leviathan Eyes and Leviathan Mouths.

The fourth wave is made up of Leviathan Claws, Leviathan Eyes, Leviathan Mouths, Naga Ritualists, Naga Warriors, Naga Archers, Saltspray Dragons and Oni.

Tactics
Simply keeping Calibos alive is not enough to accrue sufficient points. After the third wave of enemies, even the best organised teams will struggle. Killing Adepts is the best way to accrue points. Every three minutes, the point reward for killing an Adept increases by 3 points. The longer the team waits before killing Adepts, the greater the bonus will be.

It is possible for the team to split into two groups, one group to defend Calibos, the other to systematically eliminate Adepts to buff the entire team with Rage of the Sea, making the job of protecting Calibos easier. Theoretically, a single tank can eliminate Adepts for the entire team. Provided they can heal themselves and dish out enough damage to kill the elementalist Adepts, the remaining seven players can hold the fort long enough to accrue plenty of points.

Early Bugs
Although this glitch has been eradicated, previously people could get insanely high scores in this mission without doing any work. This would happen by entering the mission (preferably alone) and just walk backwards towards the gate. The groups would come and kill the priest, but for an unknown reason the mission would not end. The user would get a hold out bonus of two for every minute they stood there. This made it possible for players to leave their computers idle while gaining extremely high scores.
