Lahmu Boss Setup

Here is a breakdown of the battle preparation against the boss:

Carry HP and MP recovery items

Before engaging the boss, bring HP and MP recovery items in case your party runs out of HP and MP during battle. Also, don’t forget Ailment recovery items such as Amrita Soda.

Max your Magatsuhi Gauge

In addition, make sure that your Magatsuhi gauge is already maxed. Having it maxed prior to battle is helpful in setting up your offense. Also, having a Miracle skill, Magatsuhi Wellspring, will provide your party HP and MP recovery at the start of your party’s turn.

Assign Nahobino Fire, Force, and Light skills

Make sure to import Fire, Force, and Light skills if you can in order to exploit the weakness of the boss. Otherwise, you can rely on your ally demons to have those skills for you. To add, complement your offense with strength-based elemental skills such as Fire/Wind/White Dracostrike.

Furthermore, put in Support and Passive skills to boost damage if there are still skill slots remaining. Recovery skills are optional if your active party members do not have these skills. This is to sustain the party during battle.

Attach resistances to Nahobino that nullify Ice, Elec, Dark, and Ailment skills

With the Divine Amalgamation Miracle, Nahobino can implant new resistances from essences. Add to Nahobino resistances that can Reflect/Absorb/Void/Resist Ice, Electricity, Dark, and Ailment skills.

Pick ally demons that can counter Ice, Elec, Dark, and Ailment skills

Bring party members can innately Reflect/Absorb/Void/Resist Ice, Electricity, Dark, and Ailment skills if possible. If you can’t, make it a point that their weaknesses are covered during battle. You can make use of Ice, Electricity, Dark, and Ailment Block skills or make use of Dampener items.

Add demons that can use Phys, Fire, Force, and Light skills

Similarly, add demons to your active party that can use Physical, Fire, Force, and Light skills. If they don’t have access to those skills, utilize Essence Fusion to grab those skills from demon essences.

Since the boss fight is in three phases, have Force and Light skill users deal with the first and second phases. Then, switch to Fire skill user to clear the third and last phase.

Lahmu’s Tentacles Boss Strategies

Here is a breakdown of the battle strategies against the boss:

Start with multi-target Force and Light skill users

Assign to Nahobino party members that can deal Force and Light damage to more than 1 foe. Preferably those who have their own Charge/Concentrate and Tarukaja skills.

Pass action to support demons

If you start the battle with Nahobino and don’t have access to debuff/buff Support skills, make use of the Press Turn System and pass your turn to demon allies that can use debuff Support skills.

Land debuffs

Land debuffs on the boss while leaving some MP for offense and recovery. Debuffs are in the form of attack power decrease (Matarunda), defense power decrease (Marakunda), and hit/evasion power decrease (Masukunda). These debuffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Masukunda first. Followed by Matarunda and Marakunda.

Cast buffs

Cast buffs on your party members as well. Buffs can be in the form of attack power increase (Tarukaja/Matarukaja), defense power increase (Rakukaja/Marakukaja), and hit/evasion power increase (Sukukaja/Masukukaja). These buffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukukaja/Masukukaja first. Followed by Rakukaja/Marakukaja and Tarukaja/Matarukaja. You may also use Charge/Donum Gladi and Concentrate/Donum Magici buffs to boost your party’s damage even further if available.

Use Force and Light skills against Lahmu’s Tentacles

Lahmu’s Tentacles are weak against Force and Light skills which Nahobino and his ally demons can capitalize on. The damage will be higher if the party is buffed with Tarukaja/Matarukaja and Concentrate/Donum Magici.

Heal allies

Keep the party’s HP sustained by using healing skills. Especially when other party members are getting overwhelmed by enemy damage.

Lahmu Base Form Boss Strategies

Here is a breakdown of the battle strategies against the boss:

Change damage dealers to single-target Force and Light skill users

After clearing all the tentacles, switch your damage dealers to single-target Force and Light skill users. Preferably those who have their own Charge/Concentrate and Tarukaja skills.

Land debuffs

Land debuffs on the boss while leaving some MP for offense and recovery. Debuffs are in the form of attack power decrease (Tarunda), defense power decrease (Rakunda), and hit/evasion power decrease (Sukunda). These debuffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukunda first. Followed by Tarunda and Rakunda.

Cast buffs

Cast buffs on your party members as well. Buffs can be in the form of attack power increase (Tarukaja/Matarukaja), defense power increase (Rakukaja/Marakukaja), and hit/evasion power increase (Sukukaja/Masukukaja). These buffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukukaja/Masukukaja first. Followed by Rakukaja/Marakukaja and Tarukaja/Matarukaja. You may also use Charge/Donum Gladi and Concentrate/Donum Magici buffs to boost your party’s damage even further if available.

Activate Magatsuhi skill

Unleash the Magatsuhi skill such as Omagatoki: Critical to boost your damage even further. Make sure to use it once debuffs and buffs are already set. Activate the Magatsuhi skill on Nahobino’s turn and you will have up to 8 possible actions against the boss.

If you already unlocked the Race Transcendence Miracle skill, you can also use other Magatsuhi skills held by other party members.

Use Force and Light skills against Lahmu

Lahmu is weak against Force and Light skills which Nahobino and his ally demons can capitalize on. The damage will be higher if the party is buffed with Tarukaja/Matarukaja and Concentrate/Donum Magici.

If you are setting up for Wind/White Dracostrike, cast Charge/Donum Gladi instead to boost the damage.

Use Phys skills against Lahmu

Lahmu does not have resistance against Physical skills so add party members that specialize in this skill type. The damage will be higher if the party is buffed with Tarukaja/Matarukaja and Charge/Donum Gladi. Also, use Nahobino’s Aramasa skill against the boss constantly while you’re not commanding him to set up debuffs or buffs or healing.

Heal allies

Keep the party’s HP sustained by using healing skills. Especially when other party members are getting overwhelmed by enemy damage.

Lahmu White Form Boss Strategies

Here is a breakdown of the battle strategies against the boss:

Switch single-target damage dealers to Fire skill users.

After defeating the base form of Lahmu, switch your damage dealers to Fire skill users. Preferably those who have their own Charge/Concentrate and Tarukaja skills.

Land debuffs

Land debuffs on the boss while leaving some MP for offense and recovery. Debuffs are in the form of attack power decrease (Tarunda), defense power decrease (Rakunda), and hit/evasion power decrease (Sukunda). These debuffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukunda first. Followed by Tarunda and Rakunda.

Cast buffs

Cast buffs on your party members as well. Buffs can be in the form of attack power increase (Tarukaja/Matarukaja), defense power increase (Rakukaja/Marakukaja), and hit/evasion power increase (Sukukaja/Masukukaja). These buffs can be accessed by Nahobino and any demons in your party.

Prioritize on landing Sukukaja/Masukukaja first. Followed by Rakukaja/Marakukaja and Tarukaja/Matarukaja. You may also use Charge/Donum Gladi and Concentrate/Donum Magici buffs to boost your party’s damage even further if available. Since the boss will keep on using its Silt of Ruin skill against your party, cast -kaja buffs again or Dekunda to remove its effect during battle.

Cure Confusion Ailment inflicted to the party

If a party member got inflicted with an Ailment such as Confusion, make sure that you have access to Ailment recovery skills such as Patra or Me Patra to cure it. You can also use status recovery items such as Amrita Soda to remove them if available. Ailment recovery skills can be accessed by Nahobino and any demons in your party.

Activate Magatsuhi skill

Build up your Magatsuhi gauge again through missed attacks of the boss. While in this process make sure that the party is sustained with heals and buffs.

Use Fire skills against Lahmu

Lahmu is weak against Fire skills this time which Nahobino and his ally demons can capitalize on. The damage will be higher if the party is buffed with Tarukaja/Matarukaja and Concentrate/Donum Magici.

If you are setting up for Fire Dracostrike, cast Charge/Donum Gladi instead to boost the damage.

Use Phys skills against Lahmu

Lahmu still does not have resistance against Physical skills so keep party members that specialize in this skill type. The damage will be higher if the party is buffed with Tarukaja/Matarukaja and Charge/Donum Gladi. Also, use Nahobino’s Aramasa skill against the boss constantly while you’re not commanding him to set up debuffs, buffs, or healing.

Heal allies

Keep the party’s HP sustained by using healing skills. Especially when other party members are getting overwhelmed by enemy damage.
