Decadent False God Persona 5 Royal Weakness

Stuck on the Decadent False God fight in Futaba's Palace? We've got you covered with the Decadent False God's weakness and best Personas to fight with.

The Decadent False God is one of Persona 5 Royal's most challenging boss fights. Luckily, our Decadent False God weakness guide is here to save the day. 

Of the many ways Persona 5 Royal is different from Persona 5, Will Seeds are among the most noticeable. They're located in new areas of each Palace, but more importantly, the third is always locked behind a seriously tough mini-boss fight. The last Will Seed in Futaba's palace is guarded by the Decadent False God.

It's technically just a slightly weaker form of the strong Empress Persona Alilat, but it doesn't have all the same weaknesses. Here's how to beat it.

Persona 5 Royal: Decadent False God Weakness

The Decadent False God is an ice-based Shadow, and that means its primary weakness is fire, or in Persona-speak, Agi skills.

Alilat is usually weak to Curse skills too, but the Decadent False God doesn't share that weakness. Don't waste your time with Curse skills.

Decadent False God has strong ice/Bufu skills coupled with the Concentrate skill. That one doubles the power of magic-based moves.

Ann is a natural choice for a party member, but she's also weak to ice. You'll definitely want to bring the Ring of Vanity formed from Madarame's Will Seeds to negate that weakness.

Best Personas for Decadent False God Battle

By this time, you may or may not have access to a Persona that resists or repels ice. Mitra (Phoenix x Fuu-ki) nullifies it, and you can fuse it at Level 33. Unicorn does too (Setanta x Nekomata OR Yaksini x Jikokuten), but you'd need Special Handling from the Strength Confidant since it's Level 39.

Kurama Tengu is another option, but at Level 31, it's not the most practical choice for this point in Futaba's Palace.

Alternatively, you could keep Ann out of the party, put the Ring of Vanity on Joker, and then use Agi skills from Joker's Personas or just hit Decadent False God with attack items like the Fire Magatama or Molotov Cocktail.

Anyone can use these, and it results in an All-Out Attack each time, assuming Joker isn't incapacitated.


Once you've finished the fight, you'll get the final Will Seed in Futaba's Palace. It eventually turns into an item that increases the wearer's Agility, which also increases their chance of dodging attacks. In short, it's worth the trouble.

That's all you need to know for the Decadent False God's weakness. Be sure to check out our other Persona 5 Royal guides too, including:


Josh Broadwell started gaming in the early '90s. But it wasn't until 2017 he started writing about them, after finishing two history degrees and deciding a career in academia just wasn't the best way forward. You'll usually find him playing RPGs, strategy games, or platformers, but he's up for almost anything that seems interesting.
