Okinawa Jail Lock Keeper Strategies

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

Carry 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 the Lock Keeper. Debuffs can be in the form of attack power decrease (Tarunda), defense power decrease (Rakunda), and evasion/critical evasion decrease (Sukunda). These debuffs can be accessed by Joker (from Arsene and other Personas) and Sophie.

Cast Buffs

Follow-up the debuffs with party member 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 Fox.

Use Bless and Curse Attacks

The Multi-Arms Lock Keeper is weak to Bless and Curse attacks which Sophie, and Joker can handle. 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.

Deal Technical Damage using Phys, Gun, and Nuke Attacks

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

Capitalize on Terrain Gimmicks

There are two terrain gimmicks accessible in the monitoring room. Quickly transfer on them and use Phantom Dash to hurt the boss.

Terrain Gimmick	Strategy
Hanging Scaffolding	Lure the Lock Keeper near the scaffolding. Then, use the terrain gimmick to hurt the boss from above.
Broken Steel	Lure the Lock Keeper near the steel. Then, use the terrain gimmick to hurt the boss nearby.

Unleash Showtime Attacks

While engaging the Multi-Arms Lock Keeper, 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.
