The first trial, the trial of balance
involves balancing the elements. Each element's room has a number of non-aggressive elementals. When one elemental is killed, another is spawned in the next element's room clockwise around (metal->water->wood->fire->earth->metal.) All elementals are [?] level with over 50 million HP. When the elements are balanced, a boss is spawned.
(Boss have 100m hp, and a nasty AOE)
Technique: Concentrate on one mob at a time, one room at a time. Have someone calculate what the balance point is, and keep track of how many in which rooms you need to kill. Do not use any AoEs (other than Chromatic Healing Beam), attack AoEs will get you killed by attracting the attention of other mobs, and BB it seems will eventually get aggro from non-attacked mobs. Sage Soul Degeneration will greatly speed kills.
Metal Elementals These have physical and magical AoEs, and a lightning attack. One of the harder to defeat elementals because of the frequent AoEs.
Water Elementals These have a water attack and a (rarely used) AoE.
Wood Elementals These have a ranged (physical?) attack and AoE poison.
Fire Elementals These have an AoE seal. Possibly the easiest element to do.
Earth Elementals These have a reflect buff. Assassins beware! Standing at maximum melee range will keep you safe from reflect 90% of the time. Reflect may be purged.
2. Trial of Defense
The Trial of Defense involves erecting defenses to kill a train of mobs that walk through the rooms.
3. Trial of Towers
The Trial of Towers tasks you to defend 3 towers and their guards from wave after wave of enemy attacks.
4. Trial of Duty
The Trial of Duty involves defending an NPC from 4 totems that surround it. Some of the totems are immune to magic damage while some are immune to physical damage so you need a good mix of classes and high DPS.
5. Trial of Elements
The Trial of Elements is similar to the Trial of Balance in that you have to balance 5 different rooms. The health of the rooms is continuously dropping and you have to raise them all up to above 100 to summon the boss.
6. Trial of Eternity
The Trial of Eternity centers around a large collection quest. You are tasked with assembling a complete manuscript from various fragments scattered around the stage.
7. Trial of Sacrifice
The Trial of Sacrifice tasks you to kill a certain a certain number of mobs. The mobs spawn in groups and run around the perimeter of a circular room. They have no attack but they do have a lot of HP.
8. Trial of Exodus
The Trial of Exodus involves freeing NPCs that are trapped in a jail and escorting them to safety.
9. Trial of Salvation
In the Trial of Salvation, wave after wave of enemy forces crash into your party. The enemies all have very large AoEs which can quickly wipe out a faction if they aren't killed fast enough. To defend against them you can erect large angels that can soak up a lot of damage. You have to kill a certain number in a limited time to summon the boss.
