Primary
The idea of this mission is to defeat the above mentioned six teams in three arenas. In the first arena you will meet one team, then in the second, two together, and finally three teams. Each opposing team is varied in number and formation, but will have one boss (which the team is named after) and one priest who resurrects fallen team members.

For starters, it is recommended that you kill all 5 Sand Giants on your way to the opposing teams which will give you a 10% morale boost (2% from each giant). The Sand Giants are at the locations marked with A on the map.

Continue on the obvious path forward, mostly south towards a passage over a wrecked ship. A few devourers should be in your way. Continue along the path over the ship and you'll fight another set of devourers, and soon make your way into an oasis of sorts.

Talk to the Ghostly Hero to begin facing the first boss team, and a timer will appear. The timer is not counting against you, it is actually an excellent tool to time your attacks.

The first team has three groups. Focus on one group at a time and take out the spell-casters first. Use the timer in order to plan your attack on the enemy priest. At each multiple of two minutes (2:00, 4:00, etc.), the enemy priest, if still alive, will resurrect all his fallen teammates. You need to make sure you kill the enemy priest before the timer hits a multiple of two minutes. Then the team is defeated (the popup says, 'annihilated') once you have killed the last of its members. One of the issues with the priest resurrecting these fallen enemies is that they spawn in his shrine, making it harder to kill him.

Tip: The usual scenario is to take out one or two groups blocking your way, then have at least three to four members--if not the entire team--break through the enemy and kill the priest. Then resume taking on the remainder of the enemy team. A good rule of thumb is to begin the concerted attack on the priest at around 1:30 (and for later teams, an even two-minute multiple of 1:30, e.g., 3:30, 5:30, etc.).

Tip: If you are worried about being unable to finish off a priest before he revives his fallen comrades (timer nearing a multiple of 2 minutes), then retreat. The revived patrols will move out and you can engage them again. Running in and desperately trying to throw everything at the priest only to be caught in that respawn is a sure way to fail. Regrouping and redoing a team is easier than restarting a mission.

The fight in the next arena is against two teams, so you should focus on one team at a time. The Ghostly Hero will open the door to the arena when he nears it. When the door is opened and you enter the arena, enemies will approach you from both sides. Do not fight both teams at the same time, instead, stick to the left wall and engage the team on the left (southeast). You may want to wait until 2:00 before actually initiating the fight, though if your team is ready and you have a good target caller, this is not usually necessary.

After finishing the first of the two teams, wait until the timer is near a two-minute interval (4:00, 6:00, etc.) before proceeding to the next team.

Tip: When moving on to a second or third team in a single arena, i.e., while the timer is still going, judge your team's ability to take down an enemy quickly. You may be able to 'cheat' a bit and engage the next team at anywhere from 10 to 20 seconds before an even two-minute interval, as long as you do not drop the first enemy before the two-minute interval is reached. Note that casters will fall quicker than warrior or ranger types.

Continue on to the last arena against three teams, again focusing on and taking out one team at a time. As before, kill the priests before an even two-minute interval. To the left, the team starts with a hole that allows players to rush in and kill its priest.

The boss in one of the final three teams (usually the leftmost one at E4) is a monk. He is an exceptionally good healer. It is best to engage his team away from him, then when only he and the priest are left, everyone on the team should focus fire on the priest. If the team has anyone who equips interruption skills (like Cry of Frustration and Distracting Blow), they should try to disrupt the boss as much as possible. Trying to kill the monk boss first is likely to be a failure as it will probably drag the battle into the next multiple of 2:00.

Bonus
The bonus objective is to clear all the enemy teams in under 10 minutes. You will know that the bonus is still achievable if King Khimaar is standing in the central area of the third trial; If he leaves before you finish, then you've lost the bonus.

After you defeat all the teams (in any order you prefer), you will receive the bonus 1000 xp, right before the mission ending cutscene.
