Mementos boss guide
Persona 5 Royal Reaper: How to Find and Beat It
The Reaper is an optional, high-risk Mementos encounter. Find it by paying attention to the area and its chain warning, then enter the fight with a healer, dependable damage, and a plan to recover when a turn goes badly.
This Persona 5 Royal Reaper guide separates finding the encounter from winning it. It covers when to try, how to prepare the party, how to read the opening, what to do about the Reaper’s lack of an obvious weakness, and which older Persona 5 tips should not be treated as guaranteed Royal strategies.
Short answer
Quick answer: prepare first, then wait in Mementos
Go to Mementos, remain in one area long enough for the Reaper to approach, and use the chain sound as a warning. Before you engage, make sure Joker can survive a heavy turn, the active party can heal or revive, and at least one Persona can deal reliable damage without relying on a free weakness knockdown. There is no universal level that makes the fight safe: difficulty, equipment, party skills, and your current save all matter.
- Treat the chain sound as the encounter cue; do not use a stopwatch as the only trigger check.
- Bring one dependable healer, a way to restore knocked-out allies, and damage from more than one source.
- If the first exchange drains your healing items or leaves two allies down, retreat and improve the build before trying again.
- Do not assume every flu-season or instant-win tip from the original Persona 5 also works in Royal.

Where to find the Reaper in Persona 5 Royal
The Reaper is an optional enemy encountered in Mementos, not a Palace route target or a Persona you recruit by negotiating. The practical search starts after you enter a Mementos area: pause your movement and listen. A rattling chain is the warning that the Reaper is nearby. If you keep moving between floors or menus, it becomes harder to tell whether you are waiting for the encounter or resetting the area state.
Use the sound as a cue, not as a precise timer. Different guides quote a fixed wait, but a stopwatch is a poor substitute for observing the game state. Stay in one Mementos area, keep the screen visible, and allow time for the warning to become clear. When the Reaper appears, decide whether you are actually ready before committing. You can leave the area and return later; finding it does not obligate you to fight immediately.
If the Reaper does not appear, first check that you are in Mementos and that you have stayed in the same area. Then wait a little longer without changing floors. If the cue never arrives, reset the area by moving to another floor and trying again. This is a more useful recovery path than repeatedly changing party members while no encounter is active.
When should you fight the Reaper? Use a readiness check, not one level number
Searches for when to fight the Reaper often ask for one recommended level. That answer is incomplete. Two saves at the same level can have very different results because one has current armor, a broad skill set, and recovery items while the other has several exploitable weaknesses. Your difficulty setting and familiarity with turn management also change how much room you have to recover.
A safer decision is to check what happens when an enemy deals its strongest opening damage. If Joker can survive it, the party can restore a downed ally, and you still have a way to make progress after using a healing turn, the attempt is reasonable. If a single attack forces you to spend every turn healing, wait until your equipment and support skills improve. The goal is not to reach a magic number; it is to make one bad turn survivable.
Before entering, save your current progress and check that the active characters have the equipment and skills you intend to use. Review HP and SP, refill consumables, and remove a Persona weakness that the Reaper can punish if your options allow it. Do not spend money on a complete rebuild just to test the encounter. Make one or two targeted changes, then measure whether the next attempt is more stable.
| Readiness check | Ready when | If not ready |
|---|---|---|
| Survival | Joker can take a heavy hit and still act. | Improve armor or defenses; postpone the fight if one opening attack ends the run. |
| Recovery | The party can heal and revive without losing every action to emergencies. | Bring recovery items or adjust the active party before searching again. |
| Damage | You can keep dealing useful damage after one member spends a turn supporting. | Use a better current Persona or a different damage source; do not rely on a weakness trigger. |
| Resources | HP, SP, and consumables can cover a longer fight. | Restock and save before returning to Mementos. |
Build a stable party around roles
There is no single best party for every Reaper attempt. The dependable setup covers four jobs: Joker carries a flexible Persona, one teammate heals, another contributes reliable damage or a team buff, and the last slot fills the gap your current build has. Makoto is a natural support choice when her healing and defense tools are available. Ryuji or Ann can supply a damage direction, while another character can be more useful if their current skills cover a weakness in your lineup.
Think in roles rather than copying a late-game team list. A character who is strong on paper may be a poor choice if their SP is low or their current skill set cannot help in this fight. The same is true for Joker’s Personas: carrying several high-damage attacks does not make the setup resilient if every option shares the same weakness or leaves no room for recovery.
A practical loadout has at least one high-value attack, a way to improve your side or weaken the enemy when the opening allows it, and a recovery option. If a skill uses a lot of SP, decide in advance which turns justify the cost. Keep a lower-cost action available so you do not reach the middle of the fight with no useful option.
Role checklist
- Joker: a Persona that can take hits and provide a dependable attack, not only a glass-cannon setup.
- Recovery: one character who can restore party HP, plus an item or skill that can revive a fallen ally.
- Pressure: one steady damage source and one support action such as a team buff or enemy debuff.
- Flex slot: choose for the skills you actually have unlocked, not for a fixed online ranking.
How to beat the Reaper: a turn-by-turn plan
Start by reading the battle instead of spending the whole opening on setup. Check who can act, whether your team has taken a weakness hit, and how much HP remains after the first exchange. If the party is safe, use one support action and begin applying damage. If an ally is close to being knocked out, stabilize first; a buff has little value when the next enemy action can remove the person who needs to benefit from it.
Keep a simple priority order: prevent a knockout, revive a key ally, heal before the next dangerous exchange, then use support and damage. This does not mean healing to full after every small hit. It means setting a threshold before the battle: when a character is unlikely to survive another heavy attack, heal now. The threshold should be more conservative on harder difficulty settings or when Joker is the only source of a required skill.
Do not spend every action repeating the same attack if the result is weak. Change the damage source, use a useful support move, or make a safe recovery turn. Watch whether a tactic is actually buying more damage or preventing a turn loss. If it does neither, stop paying its SP cost. This keeps the fight readable and helps you distinguish a bad build from a bad sequence of choices.
The Reaper can punish a team that has no recovery plan, so treat a surprise knockout as a decision point. Revive the teammate who can stabilize the rest of the party, not automatically the character with the highest damage. If Joker is close to being downed, protect Joker first. One stable turn is usually more valuable than a risky burst that leaves the team unable to respond.
| Moment | Action | What to watch |
|---|---|---|
| Before the first attack | Check HP, turn order, and current weaknesses. | Do not assume an online opening strategy matches your battle state. |
| Safe opening | Apply one useful buff or debuff, then begin damage. | Avoid using every action on setup with no immediate benefit. |
| After a heavy hit | Heal or revive the character who keeps the party stable. | A low-HP Joker or healer is a stronger warning than a small SP shortage. |
| Damage stalls | Switch attack source or use support; compare the result. | Do not repeat a costly move if it is not changing the fight. |
| Two allies fall or items run out | Retreat, save, and adjust the setup. | A failed attempt is useful information; do not keep spending resources unchanged. |
Reaper weakness, old tips, and what not to assume
Players search for a Reaper weakness because a normal weakness knockdown can create a large opening. Do not build your plan around finding one. Treat the encounter as a damage and survival check: bring a reliable attack, keep the party alive, and use support turns that produce a clear benefit. If a critical hit or a specific skill creates an opening in your own battle, use it, but do not assume an elemental weakness will appear on demand.
Be cautious with status and instant-win advice as well. A tactic that works in a different Persona game, a different edition, or a particular challenge setup is not automatically a safe Persona 5 Royal method. In particular, do not plan an entire run around older Flu Season advice that claims the Reaper can simply be made to lose. If you test an unusual tactic, save first and confirm the result in Royal before spending your build around it.
The same caution applies to exact level, damage, and turn-count claims. Difficulty, equipment, character skills, and progression can change the experience. A guide can explain a reliable decision process, but it cannot promise that every save will defeat the Reaper in the same number of turns. Use your own battle feedback: incoming damage, recovery cost, and whether each attack is moving the fight forward.
Farming the Reaper and recovering after a failed attempt
Some players return to the Reaper for repeat battles or experience, but farming is only efficient once the fight is repeatable. Compare the time and resources from one clear with the time spent recovering and restocking. If each attempt empties your SP or requires a long reset, improve the party first. Do not treat a single successful clear as proof that the setup is ready for a long farming session.
If you lose, write down what actually ended the fight: Joker was knocked out, the healer ran out of SP, the team lacked damage, or a weak Persona invited repeated punishment. Change the matching part of the build, not everything at once. The calculator can help you plan a Persona route; the Persona list and skill database can check candidates and learned skills before you spend compendium money.
If the Reaper no longer appears, leave the current Mementos area and start the encounter search again. If you are deciding whether to continue a run, retreat when the party cannot recover safely rather than waiting for a lucky turn. That gives you a clean next attempt and preserves the information you learned from this one.
A short retry loop
- Save and restock before entering the encounter area.
- Record the first problem that forced a recovery action.
- Change one matching item, Persona, skill, or party role.
- Try again and compare survival, SP use, and damage before farming repeatedly.

Enter Mementos, remain in one area, and listen for the chain warning that signals the Reaper is close. If it does not appear, wait longer or change floors and reset the search.
What level should I be to fight the Reaper?
There is no universal level that guarantees a safe fight. Check whether Joker can survive a heavy hit, whether the party can heal and revive, and whether you can keep dealing damage after a support turn.

Do not rely on a standard elemental weakness for your plan. Build around dependable damage, survival, and support; take advantage of a real opening if your battle produces one.
Can you recruit the Reaper as a Persona?
This guide covers the Reaper as an optional Mementos enemy encounter. Do not confuse finding or defeating it with recruiting a Persona through negotiation.

Do not treat older Flu Season instructions as a guaranteed Royal strategy. Edition-specific mechanics can differ, so save first and verify any unusual tactic in your own Royal game.
Is farming the Reaper worth it?
