Berserk Sophie Party Build and Strategies

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

Party Build

We recommend any party member for this scripted boss fight.

Use Curse Attacks

Sophie is weak to Curse attacks which Joker can capitalize. However, don’t use elemental attacks to deal damage since this is a scripted battle.

Use Normal Attacks

Deal normal melee attacks to Sophie in order to conserve SP. You don’t need to deplete Sophie’s whole HP bar to zero since this is a scripted battle.

After the battle and a cutscene, your party returns to Jail of the Abyss. Your party will eventually return to this area to face the next boss.

Hundred-Armed Watcher Hecatoncheires 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

Inflict Mental and Status Ailments

During the first phase, start inflicting status effects to enemy shadows. Use Panther’s Marin Karin or Brain Jack to covert shadow enemies into temporary allies. You can also use Noir’s Evil Touch or Evil Smile to make shadows unable to move or take actions against your party. Lastly, utilize Fox’s Taunt to prevent enemy Personas from using elemental attacks on your party.

Deal Technical Damage using Psy Attacks

Once enemies are inflicted with mental ailments, deal technical damage by using Psychokinesis attacks. Switch between Joker and Noir to avoid running out of SP. You can make use also of status ailments such as Burn and Freeze.

Land Debuffs

After the waves of shadows are cleared, the Accomplice of EMMA will summon a Hundred-Armed Watcher in an attempt to finish off the Phantom Thieves. Start the second phase by landing multiple debuffs on Hundred-Armed Watcher and other shadows. Debuffs can be in the form of attack decrease (Tarunda or Matarunda), defense decrease (Rakunda or Marakunda), and evasion/critical evasion decrease (Sukunda or Masukunda). You may also use Debilitate for an all-in-one debuff. These debuffs can be accessed by Joker (from Arsene and other Personas), Panther, and Sophie.

Cast Buffs

Follow-up the debuffs with party member buffs. Buffs can be in the form of attack increase (Tarukaja or Matarukaja), defense increase (Rakukaja or Marakukaja), and evasion/critical evasion increase (Sukukaja or Masukukaja). Another option is by using Heat Riser which is an all-in-one buff. These buffs can be accessed by Joker (from other Personas) and Noir. 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 Panther.

Use Bless Attacks

Hundred-Armed Watcher is weak to Bless attacks which Sophie and Joker can capitalize. Adjust Sophia’s direction properly so that the area of effect reaches as many mobs as possible. After fine-tuning your position, have Sophia face the boss. Use a Bless skill to dish out some good damage while the other characters keep the boss busy.

After whittling the boss down, perform an All-Out Attack to bring it over by roughly a quarter of health. Don’t forget to use recovery skills or items for yourself and an ally or two. Unless the boss is distracted, circle around it and stick to its side. Use Bless attacks again when you are on the safe side. Bring it down to less than half to gain access to another All-Out Attack. The combined moves should be enough to bring Hundred-Armed Watcher down its knees which gives you an opportunity to finish it off with a combo or two.

Unleash Showtime Attacks

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.
