Earthlock: Festival of Magic

Story related, cannot be missed.

Near the end of the game, you'll be inside the Karba dungeon. Make your way to the center of the area and go up the ramp. Save your game here because the next Boss Fight will be one of the toughest fights you'll face. Head north to trigger a cutscene with Ichabo and Bryn that leads into a Boss Fight.

List of Ichabo and Bryn's Attacks:

• Iron Skin: Casts Reflect Shield and Physical Shield on the entire enemy party. This makes them immune to all physical damage for 3 turns and will automatically reflect any spell cast against them back at the caster.
• Axe Swing: Attacks one of your party members with a basic axe attack. Has a 25% chance of causing Glance.
• Sloth: Cast Slow on your entire party, however, you should be immune to this Devastation ability. If someone in your party doesn't have the LÿsAegis Talent equipped, they will have their health pool reduced down dramatically to like 1 or 2. If they lose that health, they need to be resurrected.
• Devastate: Inflicts Devastation status affect your entire party (you should be immune to this).
• Blade Storm: Attacks all allies with two swings of air blades emitted from Bryn's axe that has a 25% chance of inflicting Glance.
• Contempt: Reduces your entire party's Battle Bond.
• Single Out: Inflicts Slow on one of your party members.
• Armor Sunder: Bryn attacks one ally with his axe that has a chance of inflicting status effects of reduced Attack and Defense.
• Vulnerable: Reduces your entire party's Attack, Magic, and Defense.
• Elemental Storm: Casts a random AOE spell on your allies.

Boss Fight Strategy: Ichabo and Bryn

This battle is easy if your party members all have the LÿsAegis Talents equipped. I recommend having a party of Amon, Ive, Gnart and Taika. Focus on defeating Ichabo first as he's an extremely powerful foe with Devastating abilities. Have Amon use Gouge since both bosses are able to be inflicted with the Bleed status. Have Ive use Toxic Lances ++ to inflict Poison status on them. Have Gnart focus on healing by using Heal and only attacking with Whirlwind when the opportunity is right. Taika should be using her AOE abilities like Fire Breath or Predator S into a Fire Breath S for the Burning status chances. Additionally, you can cast Curse to afflict roughly about 4 different status effects on one of the bosses which will last two full turns (each effect will take 500-650 damage, times that by 4 which is a total of 2000-2600 damage!). Now, whenever you need to stall or wait for the magic and physical immunities to wear off on the bosses. Simply use healing items like Healing Elixir + which can restore 3000 health or select Rest to gain more Amri. Resurrect any fallen allies as needed and these bosses should fall. Once Ichabo is out of the picture, Bryn will easily be defeated.

When the battle comes to an end, a cutscene will trigger and Bryn reveals he was corrupted with amri by Ichabo's doing. Controlling him against his will. When this cutscene is over, head to the statue and Bryn will mention that there's an amri leak beneath the statue. Enter one of the doorways below the stairs to find a prison. Amon's uncle Benjo is in this prison, to rescue him you need to do the following:

1. Enter the elevator and use the lever.
2. Exit the elevator and head left to trigger a cutscene where Bryn absorbs a huge amount of amri.
3. When the cutscene ends use the lever on the left wall near you. This will unlock all cells.
4. Return back to the elevator and use the lever.
5. Exit the elevator and head to the right and open the 2nd door. Inside this cell is Benjo.

After reuniting with Benjo, a cutscene will play out and once it ends, the trophy will unlock.
