Navigating the sprawling depths of Mementos in Persona 5 Royal brings players face to face with various supernatural threats, but none are quite as terrifying as the Reaper. This optional superboss serves as a ultimate test of your party's combat readiness and strategic planning. Understanding how to trigger this encounter intentionally is the first step toward claiming rare rewards and massive experience point boosts.
How to Summon the Shadowy Tormentor
Unlike standard enemies that patrol the subway tunnels, the Reaper only appears when players break the established rules of exploration. To force this formidable opponent to spawn, the Phantom Thieves must remain entirely stationary on a single floor of Mementos for approximately five minutes. You will know the countdown is complete when the ambient background music fades out and is replaced by the ominous sound of clanking chains.
It is crucial to note that the spawn timer continues to tick down even if you are standing completely still inside the Mona Car. However, opening the main pause menu or checking your inventory will temporarily pause the tracking process. Once the chains begin to rattle, the boss will actively hunt your position until it corners your party on the map.
Tactical Preparation and Combat Mechanics
Conquering this supernatural entity requires a deep understanding of defensive buffs and elemental resistances. The Reaper possesses access to top-tier magical spells of every element alongside devastating instant-kill curses. Preparing your loadout with gear that nullifies bless and curse attributes will drastically reduce the chances of a sudden game over screen.
A popular strategy involves allowing the boss to ambush your party rather than striking it first from behind. When the enemy initiates the combat sequence, it is mechanically limited to taking only one action per turn instead of its standard two attacks. This simple tactical adjustment gives your support characters a much better window to maintain healing rotation and stat barriers.
The Evolution of Mementos Exploits
Longtime fans of the original version often recall utilizing a specific environmental exploit involving the flu season weather cycle to defeat the boss effortlessly. During certain calendar days, enemies could spawn with the despair status condition, causing them to automatically perish after three turns. However, developers completely removed this loophole in the definitive edition, forcing modern players to rely entirely on legitimate combat strategies.
Without the old shortcuts, optimizing your active roster with high-tier Personas becomes mandatory for survival. Utilizing team configurations that maximize critical hit chances can help down the target for powerful All-Out Attacks. Dedicated players often spend hours farming optimized gear to ensure their squad can withstand the intense damage output.
Reaping the Ultimate Endgame Rewards
Defeating the ultimate executioner grants players an incredible abundance of experience points that can instantly level up lower-tier party members. Additionally, securing victory unlocks the highly coveted Divine Pillar accessory, which significantly mitigates incoming offensive damage at the cost of evasion. Overcoming this hurdle also satisfies one of the most prestigious progression milestones required for completionists.
