Persona 5 - Experience Earnings Method: “Reaper” | Usage of the Influenza Warning [Persona 5/P5]

Information about how to gain experience in Persona 5 by using the Reaper that appears in Mementos.


Persona 5 Experience Earnings Method: “Reaper” | Usage of Influenza Warning


Super Strong Enemy Shadow
In Mementos, a strong enemy shadow occasionally appears known as the Reaper. It is a strong shadow that cannot be beaten unless you are at a fairly high level. It is advised to avoid the Reaper when it appears as it is very strong.  However, if you can knock it out, you can get the Divine Pillar accessory that halves damage and a huge amount of experience.
How to Earn Experience by Easily Defeating the Reaper
It is highly recommended to fight the Reaper during an Influenza warning. When encountering shadows during influenza warnings, including the Reaper, they have a chance of entering the battle under the effects of Despair. This will cause the shadow to succumb to despair and die after three turns.

Procedure of earning value

  1.  Go to Mementos on a day of “Influenza Warning ” .
  2. Move to a waiting room and save progress.
  3. After saving, move to an area and stand still until the Reaper appears.
  4. When the reaper emerges, the battle will start.
  5. Continue to fight if the reaper is under Despair. If it is normal, escape the fight and challenge them again.
  6. In desperate state, wait out turns by guarding
  7. If the enemy collapses due to the effect of despair, move to the waiting room and save.
  8. After saving, move to the area and wait until it appears again.
  9. Repeat the above procedure.

When under the effects of despair, the Reaper will self destruct after a few turns. Because you can get a large amount of experience when winning, this can be a valuable method when grinding levels.

Notes on this method
Special Skills are not necessary to earn experience.
Take note of influenza warnings, as it only occurs at certain periods of time.
Influenza warnings occur only in the following periods:

Influenza Advisory Periods
11 / 13-11 / 15
12 / 8-12 / 9

These times are the only periods of time when influenza warnings occur. Since it is a very short period, those wanting to try need to pay careful attention to the time. Even during the influenza period, the Reaper’s Despair is random. The method may have to be repeated if the Reaper starts the fight without Despair.

on easy difficulty he gives 75kexp and on merciless he gives 28kexp


Really?! Wow, that is cool!

Phantom Thieves

so that’s the reason why the average level for players during that period are way higher than mine…
but I managed to defeat the last dungeon/last boss easily without defeating this optional boss. I guess I will try to defeat him on NG+


Game breaker, if you take narcissus with ambient aid for greatly increases success rate of ailments during rain, pollen, or flu (very easy despair)

[…] Technically, there are two optional superbosses in Persona 5. The first is everybody’s favorite dual gun-wielding AFK-killer, the Reaper. It’s available to fight as soon as you gain access to Mementos, and all you have to do to get its attention is to go idle while on the field. Eventually, you’ll hear the distant sound of chains, which means that the Reaper’s coming for you. Obviously, it’s one of the toughest bosses in the game, and should pose a huge threat to anyone, especially on higher difficulties. (There is a neat little trick to killing it easily, though…) […]


Game breaker, I would only suggest doing it on your New Game+ playthrough because the rest of the game is hilariously easy after you do it even once

But still, an awesome trick, now if only farming gold were so easy, the Memento boss trick is so annoying and random STOP THROWING ME MUSCLE DRINKS lolol


*same commenter as comment listed at 9:15*
A thought occurred to me, but a step you might want to include for ease of use in this strategy is perhaps have escape items (cannot remember the name of P5’s escape item at this time, as I am currently still trying to use this method to farm up XD But its a thought worth noting even without the name of the item)


Tried this for the first time just now. First time I found him, almost got wiped out. Second time… SCORE! XD I am not ready to face him normally by any means, but doing this was no big deal at all. Just save in the waitroom and keep trying if you fail to survive an encounter without.


I use it cos I’m on ng+, for first playthrough it isn’t advisable


I tried this method on influenza day but the odds of a reaper with despair status is very low. I enagged and escaped more then 15 times without it happening. It’s possible they patched the US version.


I just did it and it worked for me
