Mom Bomb: Water, Explosion & Great Bombs

What should you equip before Mom Bomb?

Bring Water and avoid relying on Fire. Terra’s Water or Cloud’s Water Surge can supply the needed element if you obtained their sanctums and equipped the commands. Rain’s normal Fire-focused plan is less useful against this enemy.

Keep Fina able to recover the party, and review magic protection before the health-triggered explosion. Body Slam can also cause Paralysis, so preserve a way to restore a disabled actor.

Why did the main body become invulnerable?

The story walkthrough records a low-health transition in which Mom Bomb becomes protected, explodes and leaves four Great Bombs. Do not spend repeated attacks on a protected main body while ignoring the new targets.

The encounter guide also discusses interrupting devastating attacks. That should not be read as a guarantee that one Stagger skips the entire scripted split. This page does not promise an exact health percentage or a method for avoiding every explosion.

Complete the whole encounter

1. Use Water to build pressure on Mom Bomb while keeping the party healthy.
2. Prepare protection and recovery before pushing it into the low-health transition.
3. Read the changed target list when the explosion resolves.
4. Defeat the four Great Bombs rather than waiting for the original body to become attackable again.
5. Confirm the battle-result screen before treating the forge rescue as complete.

An HP heal and a Paralysis cure are separate actions. If the healer is disabled, use another character’s item action to restore control before assuming the party has no recovery option.

Where does the story go next?

Report to Borin and follow the northward departure toward Mobliz Shipyard. That dungeon has its own machinery and timed escape, covered in the shipyard guide. Preserve a manual save before its upper story event; Mom Bomb’s victory does not remove the need to prepare for the next sequence.
