Zephyrus Mech Strategies

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

Carry HP and SP Recovery Items

Before engaging the boss, bring a stock of HP and SP recovery items. These items can be bought from accessible vending machines, food stands, stores, and restaurants. You can also buy ingredients from Sophia’s Shop and other real-world stores. Then, cook these ingredients for additional HP and SP items through Joker’s Kitchen.

Joker’s Kitchen Guide

Engage from the sides or behind

Strafing to the side or back is generally a good strategy against Zephyrus Mech as most of its damaging attacks will only hit you if you are standing directly in front of it. The only exceptions are its cluster missiles that home in on you and its laser blasts (both ground and airborne).

Land Debuffs

Start the battle by landing multiple debuffs on Zephyrus Mech. Debuffs can be in the form of attack power decrease (Tarunda), defense power decrease (Rakunda), and evasion/critical evasion power decrease (Sukunda). These debuffs can be accessed by Joker (from Arsene and other Personas). Another option is by using Debilitate for an all-in-one debuff. This special debuff can be accessed by Joker (from other Personas) or Wolf.

Cast Buffs

Follow-up the debuffs with party members buffs. Buffs can be in the form of attack power increase (Matarukaja), defense power increase (Marakukaja), and evasion/critical evasion increase (Masukukaja). These buffs can be accessed by Joker (from other Personas), Skull, and Queen. Another option is by using Heat Riser for an all-in-one buff. This special buff can be accessed by Joker (from other Personas) and Wolf. You may also use Charge and Concentrate buffs to boost your damage even further if available. These buffs can be accessed by Joker (from other Personas) and Skull.

Remove Enemy Buffs

Zephyrus Mech has an all-in-one buff skill similar to Heat Riser. In order to remove it, use a Dekaja debuff skill. The debuff can be accessed by Joker (from other Personas) and Wolf.

When facing the boss again for Painful Past requests, it may use the buff skill repeatedly. Always check the boss’s data to ensure that the boss will not gain an advantage from you.

Use Elec and Nuke Attacks

Zephyrus Mech is weak to Electricity and Nuclear attacks which Skull, Queen, and Joker can capitalize. Continue on using elemental attacks in order to break the shields and stagger the boss. Make use of narrow range elemental skills if you’re close and wide range elemental skills if you’re far from the boss.

Avoid Special Moves like Supernova

While damaging the boss, it will unleash its unique attacks to your party. For the first phase of the battle, the boss will rely on his mech suit skills to do the damage.

Special Move	Strategy
Rocket Punch	Dash quickly to evade the attack.
Homing Missiles	Keep going in circles until there are few missiles left in the area.
Pounce Attack	Move backward and double jump to avoid getting hit.
Prominence Ray	Lure the beam attack to target a corner. Then, move away and hit the back of the boss.
Supernova	Run to the side as the lasers have somewhat good tracking. If you are out of range of the attacks, you will be targeted by homing missiles instead. Don’t stay in the ledges.
Double Laser	Go in-between the legs of the boss to avoid getting hit. You can also double jump.

Capitalize on Terrain Gimmicks

There is only one terrain gimmick accessible during the first phase of the boss fight. Look for a capture point to get near to it.

Terrain Gimmick	Strategy
Turret	Use the turret to temporarily stun Zephyrus Mech while it recovers from overheating. This gives you time to press on the offense before it can retaliate.

Unleash Showtime Attacks

While engaging Zephyrus Mech, you may build up your showtime gauge. When it’s available, unleash the showtime attack against the boss. If Joker’s showtime attack is available, make sure he has the right Persona that can capitalize on the weakness of the boss. Also, there is a consumable item that will quickly boost your Showtime gauge build up so feel free to use it against the boss.

Akira the Hero Strategies

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

Party Build

The party is still the same and cannot be changed mid-battle.

Consume HP and SP Recovery Items

Before engaging the boss, replenish each of your party member’s lost HP and SP.

Land Debuffs

In similar fashion, land debuffs on Akira the Hero. Either use a -nda buff or Debiliate. These debuffs can be accessed by Joker (from Arsene and other Personas) and Wolf.

Cast Buffs

Likewise, cast party member buffs to all party members. Either use a -kaja buff or Heat Riser. These buffs can be accessed by Joker (from other Personas), Skull, Queen, and Wolf. You may also use Charge and Concentrate buffs to boost your damage even further if available. The buffs can be accessed by Joker (from other Personas) and Skull.

Keep using Elec and Nuke Attacks

Same with Zephyrus Mech, Akira the Hero is also weak to Electricity and Nuclear attacks. However, the boss loses his resistances to Fire and Ice attacks. Bombard him with skills using Joker, Skull, and Queen’s elemental attacks.

Capitalize on Terrain Gimmicks

There is only one terrain gimmick accessible during the first phase of the boss fight. Quickly transfer on them and use Phantom Dash to hurt the boss.

Terrain Gimmick	Strategy
Zephyrus Mech Broken Limb Parts	Destroy the broken part to unleash an Electricity attack as well as  inflict Shock status on Akira the Hero.
Zephyrus Mech Broken Wing Parts	Jump from the broken and unleash an Physical attack on Akira the Hero. Effective when the boss is under Shock status.

Deal Technical Damage with Phys, Gun and Nuke Attacks

When the boss is inflicted with a status ailment such as Shock, deal technical damage by using Physical, Gun, and Nuclear attacks. Have all party members switch turns in dealing Physical and Gun attacks while Joker and Queen consistently heals the party. Also, switch between Joker and Queen to avoid running out of SP.

Avoid Special Moves like Supernova

While damaging the boss, it will unleash its unique attacks to your party. For the second phase of the battle, the boss will rely to sword skills to do the damage.

Special Move	Strategy
Justice Slash	Akira the Hero mainly uses melee attacks with his sword and will often perform a three-strike combination. His swings are quite slow but have wide range so dodge to the side to avoid getting hit. The boss can also fire lasers from his sword.
Dynamic Meteor	Akira the Hero will do a quick jump that sends a shockwave down the floor. Use double-jump to avoid getting hit by the waves.

Unleash Showtime Attacks

While engaging Akira the Hero, you may build up your showtime gauge. When it’s available, unleash the showtime attack against the boss. If Joker’s showtime attack is available, make sure he has the right Persona that can capitalize on the weakness of the boss. Also, there is a consumable item that will quickly boost your Showtime gauge build up so feel free to use it against the boss.
