You're standing in the Velvet Room, Igor is grinning his creepy grin, and you've got a handful of cards that feel totally useless. It happens. Persona 5 is a massive game, and managing your roster is basically a full-time job if you want to actually survive the later Palaces. Most people treat their Personas like Pokémon—catch 'em all, level 'em up, hope for the best.
That is a huge mistake.
This Persona 5 persona guide isn't about just listing every demon in the game. You can find a wiki for that. This is about the "why" and the "how" of fusion, the stuff the game doesn't really tell you until you've already wasted twenty hours building a Jack Frost that gets one-shot by a random Berith.

The Fusion Trap and the Public Execution Secret
Fusion is the heart of the game. If you aren't executing your "friends" regularly, you're falling behind. The most common pitfall? Keeping a Persona too long because you like the design. Arsenic looks cool, right? Sure. But he’s functionally dead weight by the time you hit Kamoshida’s crown room.
You need to be looking at Arcana levels constantly. If you’ve spent time hanging out with Ryuji, your Chariot fusions get a massive XP boost. This is common knowledge. What people miss is the Network Fusion (Public Execution) mechanic. Honestly, it’s a gamble, but it’s how you get the truly broken skills like Almighty Boost or Magic Ability. You trade one of your Personas for a random one from another player online. Sometimes you get garbage. Sometimes you get a Level 90 Messiah when you’re only Level 40.
It feels like cheating. It kind of is. But in a game that lasts 100+ hours, you take every advantage you can get.
Elements vs. Stats
Stop looking at the Strength stat for a second. Look at the resistances.
A Persona with 40 Strength but a weakness to Fire is a liability. Why? Because the "One More" system in Persona 5 is brutal. If an enemy hits your weakness, they get another turn. Then they hit it again. Then you’re dead. This is why the Persona 5 persona guide community obsesses over "Null," "Repel," and "Absorb" traits. Your goal isn't just to deal damage; it's to be untouchable.

Advanced Fusion: The Gallows and the Alarm
In the original P5, things were simpler. In Persona 5 Royal, everything changed because of the Fusion Alarm.
When that red light starts flashing in the Velvet Room, everything gets weird. If you fuse during an alarm, the result is usually stronger, but there’s a high chance of a "fusion accident." Most players restart when they see an accident. Don't.
Accidents during an alarm can result in Personas that have entirely different skill sets than what you intended—often high-tier skills you shouldn't have access to yet. It’s the fastest way to "power-level" your team without grinding in Mementos for six hours straight.
Then there's the Gallows. You sacrifice one Persona to give XP to another.
It sounds simple.
It's actually the key to min-maxing.
If you want a Pixie that can nuke a God, you use the Gallows. You save your game, sacrifice a high-level Persona, and check which stat got the boost. If it didn't go into Magic, you reload. It's tedious. It's boring. But it’s how you build a "Perfect Persona."
Essential Personas for Every Mid-Game Build
You don't need a 12-slot roster of attackers. You need utility.
- Shiki-Ouji: This is the MVP of the early-to-mid game. Why? He naturally nullifies Physical, Gun, Bless, and Curse damage. He makes the third and fourth Palaces a joke. Fuse him as soon as you hit Level 18.
- Matador: Not just for the memes. His Swift Strike (if you're playing the original) or high Agility makes him a great physical sweeper.
- Daisoujou: His Samsara skill has a ridiculously high chance of an instant kill on all enemies. It saves so much SP during dungeon crawling.
The "Invisible" Math of Social Stats and Fusion
Your social life in Tokyo isn't just for dating. It’s the engine for your Personas. Every time you rank up a Confidant, you’re basically adding "free levels" to any Persona you fuse under that Arcana.
Think about it this way:
A Rank 10 Confidant gives you enough XP to jump a Persona 5 or 6 levels instantly upon birth. This often unlocks their most powerful skills immediately. If you’re trying to follow a Persona 5 persona guide and your fusions feel weak, it’s probably because you’re ignoring your friends. Spend time with the politician. Eat the massive burger at Big Bang Burger. It all circles back to the Velvet Room.
The Problem with "Auto-Optimize"
The game has a button to show you possible fusions. Never just pick the one at the top. You need to manually select which skills are inherited.
If you’re building a healer, you don't want to inherit Agilao. You want Invigorate or Mediarama. If you don't pay attention here, you end up with a "Jack of all trades, master of none" situation where your Personas have a mess of weak elemental spells and no passive buffs. Passive skills—the ones that boost damage by 25% or 50%—are significantly more important than having a fifth elemental attack.
Why Yoshitsune Still Rules the World
Ask any veteran. Ask anyone who has spent 300 hours in this game. They will all tell you the same name: Yoshitsune.
He is the "win button." His unique skill, Hassou Tobi, hits all enemies eight times with light physical damage. It doesn't sound like much until you realize that physical crits are the most consistent way to end boss fights. To get him, you need a specific multi-Persona fusion involving Futsunushi, Yatagarasu, Okuninushi, Arahabaki, and Shiki-Ouji.
It’s a grind to get the ingredients. It’s expensive. It’s worth every single yen.

Actionable Steps for Your Next Session
If you're feeling overwhelmed, just do these three things next time you boot up the game. First, go to Mementos and trigger a Fusion Alarm. Use that alarm to fuse a Persona you normally wouldn't, just to see what skills "accidentally" pop up.
Second, check your Compendium. Most people forget they can pull old Personas out for a fee. If you're missing a specific element, don't wait to find a shadow in a Palace—just buy a low-level one and fuse it up.
Lastly, prioritize the Fortune Confidant (Chihaya Mifune). Her "Celestial Reading" increases the chance of a Fusion Alarm occurring. It is the single most important non-combat buff in the entire game for anyone serious about their Persona builds.
Focus on resistances over raw power. Use the Gallows to target specific stats. Stop hoarding Personas you don't use. The Velvet Room is a factory, not a museum. Treat it like one and the "difficulty spikes" people complain about will completely disappear.
