How to Beat Liquid Thunder

[1] Use Lid Wisely.

Liquid Thunder Stone

At this point in Final Fantasy Resonance, your Earth type attacks are extremely limited. Fortunately, your new party member, Lid, has two Earth-type spells that can deal extra damage and increase Liquid Thunder's stagger gauge easier than others: Stone and Mechabo Kick.

Lid joins the party at Lvl. 11. So heading straight to fight Liquid Thunder, who is a higher level, may make the fight more difficult. Be sure to take extra care of Lid so you can consistently deal Earth-type damage to the boss.

Warrior of Light's Vision also has the Stone Blade ability, so there is a third Earth-type attack option for you.

[2] Lightveil, Shellga, Multi-Cover, and Esuna are Great Restorative and Defensive spells.

Liquid Thunder Shellga

Liquid Thunder casts strong lightning spells and can inflict paralysis. Spells that mitigate or redirect damage to more durable members of the party are recommended to protect your members, especially the fragile ones. Spells like Multi-Cover and Shellga will be your main defensive spells.

Lightveil and Esuna are great for combating paralysis, as the former raises status ailment resistance and the latter cures paralysis.

Restorative spells such as Cure or even First Aid are useful, but timing it correctly is key, as all members may need healing, and distributing heals to the party instead of one target may actually be more of a detriment to the success of the fight than useful.

[3] Bring Enough Restorative Items.

Since Liquid Thunder deals tons of damage, be sure to bring enough healing items like Potions and Healing Springs. Bring Phoenix Downs as well, as you may never know how bad things can get despite your preparations, and one party member might go down.

Try to use spells and items tactically to reserve your items in the inventory and MP.

[4] Watch out for the Gigavolt Move!

Liquid Thunder Giga Volt Prep Charging Electricity

Once you whittle down Liquid Thunder's health to below half HP, it may prepare to cast its strongest lightning spell, called Gigavolt.

Fortunately, you have time to interrupt or brace for the attack, as it will take one turn to charge, and you will be prompted with a text saying "Charging Electricity!"

Interrupt the spellcast by staggering it, or ensure your party (or key members) survive the attack by healing them to decent HP and using defensive abilities like Shell, Shelga, and Cover.
