Earthlock: Festival of Magic

Story related, cannot be missed.

Make your way to Ichabo while trying to avoid as many shadow clone figures that look like your party. If you do make contact with these shadow clones, you'll have no choice but to fight them as you cannot escape from the battles. Once you get to the end of where the greenish yellow light is at, a cutscene will trigger and you'll face the final Boss Fight of the game.

List of Valvur Ichabo's Attacks:

• Weaken: Attacks one ally with a winged blade.
• Eviscerate: Attacks all allies with its winged blades and has a chance of inflicting Bleeding and causing Glance.
• Cocoon: Casts Reflect Shield on himself. All magic cast against him will be reflected back at the caster.
• Burning Torment: Attacks the entire party with flares of fire that can inflict Burning on the party members.
• Corruption: This does nothing, to be honest as it only ends the Cocoon ability. When this happens, you can once again use magic abilities against him.
• Sacrifice: Sacrifice one of his shadow clones to restore his health and boost his abilities such as Magic Attacks.
• Total Corruption: Attacks the entire party with a powerful magic attack. This attack is strong enough to deal about 3600-5200 worth of damage depending on your party members Magic Defense stats. Gnart and Taika should have high stats to withstand about 3600-4000. Amon and Ive will end up taking about 5000-5200 as their Magic Defense should be naturally lower compared to those two. If they die, quickly revive them using Kiss of Lÿs items.
• Winged Blades: I have no idea what this really does, but the boss' body position will go lower as if he's preparing another powerful attack. I recommend you use Healing Elixir + to restore weaken allies' health.
• Poisoned Torment: Attacks the entire party with flares of poison that can inflict Poison on the party members (if hit by this, have each member use a Prevent Poison item).

Boss Fight Strategy: Valvur Ichabo

I recommend a party of Amon, Gnart, Ive, and Taika. You want Amon to use Gouge for the Bleeding status effect and have Ive use Toxic Lances ++ for Poison status effect. Have Gnart focus on healing with Heal and casting Whirlwind when given the chances. Finally, have Taika focus on casting Curse for multi-status effects and resting to recharge them back for another casting. Curse will do roughly 2300-2400 worth a damage for 2 different turns. Sometimes you can use Taika for healing purposes such as having him use Healing Elixir + to heal 3000 health to an ally. When Valvur Ichabo uses the Cocoon ability, do not use any magic attacks but physical attacks are still okay to use. Have Amon keep using Gouge at all cost and resting if needed to recharge it. The other characters can focus on healing with items or use basic attacks until the Cocoon comes to an end. That is pretty much the entire battle, Amon is the key character, Taika's Curse useful when it's able to be cast, Ive poison helps with the damage over time, Gnart keeps everyone alive whenever he has his Bond ready for healing purposes. Eventually, the Valvur Ichabo will be defeated as long as you keep this up. It should be noted that sometimes a shadow clone figure(s) of the party will spawn. Simply kill these clones as they appear in the fight. I recommend having Taika use her Predator S into Quake S as this has a chance of Stunning the shadow clones and skipping their turns.

After Ichabo is finally defeated, you have beaten the entire game! Enjoy the ending and the cutscenes that follow as the trophy will unlock before the ending credits rolls.
