Elnath Trial: Which Arm Should You Defeat Last?

What should you bring for the tome trial?

Buy the Ancient Tome from a chapter-8 merchant ship for 45,000 gil, then inspect the matching Chamber of Arms pedestal. The standard Elnath trial restores Last Resort.

Bring Lightning, both physical and magic damage, recovery and protection for party-wide attacks. The arms are not interchangeable targets.

Survive the opening countdown

Elnath warns of a special attack when its countdown reaches zero. It can also gain additional attacks after large gauge reductions between its turns. Heal before a major offensive commitment and watch Liquidate rather than assuming every partial gauge cut is free of consequences.

Choose the arm order deliberately

The Right Arm nullifies magic; attack it physically. The Left Arm nullifies physical attacks; use magic against it. Both are weak to Lightning. Defeating an arm overwrites the body’s defenses with that arm’s defensive property.

• For a physical finishing party, defeat the Right Arm last, leaving the body with magic immunity.
• For a casting finishing party, defeat the Left Arm last, leaving the body with physical immunity.

Do not leave both arms active while blindly pushing the body’s HP: its traits warn of an enrage while an arm remains. Keep the chosen finishing damage type available after the last arm falls.

Finish the body

Continue Lightning through the later body and watch Wave Cannon, Frenzied Bombardment and the extra-action buff from Haywire. Preserve healing after the warning if a Stagger cannot be reached. The stronger level-75 rematch awards Last Resort+; it does not share a guaranteed standard-trial turn script.
