Shibuya 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, 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

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), Panther, and Sophie.

Remove Enemy Buffs

The Lock Keeper has an attack power buff skill similar to Tarukaja. In order to remove it, use a Dekaja debuff skill. The debuff can be accessed by Joker (from other Personas).

Cast Buffs

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

Use Fire, Wind, Bless, and Curse Attacks

The Axe Lock Keeper is weak to Fire, Wind, Bless and Curse attacks which all party members 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.

Deal Technical Damage using Wind and Nuke Attacks

When the mini-boss is inflicted with a status ailment such as Burn, deal technical damage by using Wind and Nuclear attacks. Switch between Joker and Mona to avoid running out of SP.

Don’t Go Crazy with the Offense

The Lock Keeper will sink to the ground and teleport to another spot in order to avoid your attacks further. Don’t go all out to the boss and observe to avoid wasting HP and SP.

Unleash Showtime Attacks

While engaging the Axe 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.
