Osaka 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.
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.
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), Skull, and Queen.
Use Elec, Nuke, Bless, and Curse Attacks
The Bazooka Lock Keeper is weak to Electricity, Nuclear, Bless and Curse attacks which Skull, Queen, 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
The Lock Keeper is susceptible to status ailment skills such as Shock. If the boss is inflicted with Shock status, use a Physical, Gun, or Nuclear attack to deal additional damage to the boss.
Unleash Showtime Attacks
While engaging the Bazooka 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.
