Stamp Collection & Benefits
Collecting Mementos Stamps is a rewarding activity in Persona 5 Royal that directly impacts your ability to navigate and conquer the vast, procedurally generated dungeon of Mementos. These stamps are collected by finding Jose, a mysterious boy who roams Mementos, and can be traded for valuable items or used to upgrade the functionality of Mementos itself.
Jose can be found in various areas of Mementos. When you encounter him, he will offer to collect Mementos Stamps in exchange for flowers you've gathered. The more stamps you collect, the more valuable the rewards Jose can offer. Collecting 150 Mementos Stamps is a specific objective for the "Stamp by Me" trophy.
The primary benefit of collecting stamps is the ability to trade them with Jose for powerful items. These can include useful consumables, rare materials for crafting, or even powerful accessories that can sificantly boost your party's combat effectiveness. The specific items Jose offers change as you progress through Mementos and collect more stamps.
Furthermore, Jose can use the collected stamps to alter Mementos. By spending stamps, you can influence Mementos' environment, such as increasing the drop rate of items or the appearance rate of Shadows. This allows you to tailor Mementos to your needs, whether you're farming for specific materials, seeking out certain Personas, or aiming to complete Mementos Requests efficiently.
The "Jose's Flowers and Stamps Guide" is an excellent resource for tracking down Jose and understanding the optimal times to trade flowers for stamps. Prioritizing stamp collection alongside flower gathering will make your Mementos expeditions far more productive and rewarding, turning a potentially tedious grind into a strategic advantage.
