Best Demons to Use Against Lahmu (2nd Fight)

Eligor Hariti Nekomata
Parvati Jatayu Quetzalcoatl
Muu Shuwuu

Demons with Force, Light, and Fire attacks

SMT V Weak to fire.jpg

Lahmu's first form is weak to Force and Light attacks but after changing to his second form, his only weakness will be Fire. Be sure to cover both forms when building a team.

Quetzalcoatl is a highly recommended attacker for this fight as it is proficient on both Force and Fire skills.

Watch out for Mudo

Be careful when bringing demons weak to Dark as both Lahmu forms have Mudo attacks that can instakill them.

The first phase of this boss battle requires you to cut off all Lahmu's tentacles. Force and Light attacks that can target all foes are recommended for this phase.

Only after taking out all tentacles will you be able to attack Lahmu directly, which is also weak to Force and Light.

On the third and last phase, Lahmu will change his affinities and skills. His only weakness this time is Fire.

Bring Chakra Drops or Backup Demons

SMT V Chakra Drop.jpg

Given that the fight consists of three phases, there's a chance that you'll run out of MP from spamming skills or even have your demons wiped out.

Bring Chakra Drops for MP recovery and emergency demons that can also target Lahmu's weakness to ensure victory.

Use Sea of Stars

You can also use the Magatsuhi skill Sea of Stars to recover MP to all allies. Take note that this is only usable by demons in the Divine race.

The Divine Talisman is obtained from the Angel south of the container where you fought Loup-garou, east of Container Yard's leyline fount.

Second Form is Vulnerable to Ailments

Unlike his first form that is immune to all status ailments, you can actually inflict any ailment other than Confuse to his second form.

Since Lahmu still has resistance to most ailments (which decreases the chances), make sure to only use attacks that also deal damage in addition to inflicting an ailment so you don't waste your turn.
