How to Beat Slagworm

[1] Do not Place Lid in the Party.

Slagworm Earth Immune

The Slagworm is completely immune to Earth Magic attacks, so do not bring Lid. Lid's main attacks are Earth Magic spells, and her basic attack is extremely weak, which makes her useless in the fight.

Instead, you can place 3 Physical Attack using members and one Healer in the party for this fight.

[2] Use Wind Attacks Like Clive's Aero Surge, and Onion Knight's Aeroga.

Slagworm Wind

At this point in the game, you must already have multiple Wind affinity attacks. It is a must that you use them to stagger the Slagworm as fast as possible and have it regurgitate your swallowed party member.

Onion Knight, Clive, and Zidane have Wind affinity abilities such as Aero Surge and Aeroga. Jake also has multiple Wind affinity attacks, such as the Gale Strike.

[3] Equip Physical Counter, Cura, and Esuna.

Physical Counter will almost always trigger with every attack of Slagworm. It will repeatedly use its Physical attacks such as Flatten, CHOMP!, and Secrete Acid.

Use Esuna when your member is poisoned. Cura is extremely useful for members swallowed and regurgitated.
