Guide on How to Defeat Fratricidal Destroyer Seth

The Fratricidal Destroyer (Seth) is the first Powerful Shadow mini-boss enemy the Phantom Thieves must defeat in Persona 5 Strikers (or Persona 5 Scramble).

This shadow can only be encountered when Powerful Shadow Requests are made available by Lavenza starting on 8/24.

Clear All Powerful Shadow Requests

Below is a list of requests that unlocks the Reaper secret boss battle. The Metatron request is locked in the post-game also so you need to clear the main story first. We recommended defeating Powerful Shadows when you already unlocked Wolf as a party member in the game.

Fratricidal Destroyer Seth Strategies

Here is a breakdown of the battle strategies against the mini-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, store, 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

Land Debuffs

Start the battle by landing multiple debuffs on Seth. 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) and Sophie. Another option is by using Debilitate for an all-in-one debuff. This special debuff can be accessed by Joker (from other Personas).

Cast Buffs

Follow-up the debuffs with party members buffs. Buffs can be in the form of attack power increase (Tarukaja or Matarukaja), defense power increase (Rakukaja or Marakukaja), and evasion/critical evasion increase (Sukukaja or Masukukaja). These buffs can be accessed by Joker (from other Personas), Fox, 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) only.

Dodge Gun and Curse Attacks

Observe the boss’ upcoming moves and evade upcoming Gun and Curse attacks targeted to your character. Seth’s gun attacks has high critical rate so it could down your character immediately. Use Amrita Drop or Amrita Shower to cure the status effect.

Use Bless Attacks

Seth is weak to Bless attacks which Joker and Sophie 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.

Capitalize on Terrain Gimmicks

If Seth is beside the ice crystal or broken pillar, you can use a Phantom Dash to deal additional physical damage to the boss. You may also inflict status effects such Freeze to the boss by chance.

Deal Technical Damage using Phys, Gun, and Nuke Attacks

When the boss is inflicted with a status ailment such as Freeze, deal technical damage by using Physical, Gun, and Nuclear attacks. Switch between Joker, Fox, and Queen to avoid running out of HP.

Unleash Showtime Attacks

While engaging Seth, 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.
