Persona 5 Royal's Palaces feature a number of valuable treasures to collect, ranging from new equipment for the Phantom Thieves, to new Personas for Joker, to the ever useful and equally scarce Will Seeds. These Will Seeds are small treasures that restore the Party's ever limited SP reserves when collected, while also providing a powerful new accessory once all of them are collected.

Kaneshiro's Palace is the third dungeon players gain access to in Persona 5 Royal, and his Will Seeds are pretty well hidden, scattered throughout the flying bank and requiring players to scour every nook and cranny to obtain all three and create the Crystal of Gluttony. This guide will break down all three locations and how to reach them, and also explain how the new accessories acquired by collecting them work.

Red Will Seed Of Gluttony

This is the first available Will Seed in Kaneshiro's Palace and can be found in the Banker's Passageway. In order to do this players will need to find the room with the large vault door, and then head to the right from there and find a grapple point up to a balcony, where the sealed chamber can be found.

At some point in development, it was intended for scenes from the target's past to play whenever a Will Seed was collected, providing additional characterization and background, though these were ultimately not used in the final release of the game and unfortunately none remain in the game's code for Kaneshiro.

Green Will Seed Of Gluttony

This is the second available Will Seed in Kaneshiro's Palace, but also one of the easiest to miss if players aren't keeping an eye out. It can be accessed as soon as players gain access to the Laundering Office, by looking for a crawl space in one of the square rooms that leads into a room full of money. From here players should make their way around the room and use the grapple points to advance further until they come face to face with the sealed room that contains the Green Will Seed.

Blue Will Seed Of Gluttony

This is the final Will Seed in Kaneshiro's Palace and is right before the treasure room. In the room that functions as a giant lock players can find a small area blocked off by a wall. This can be accessed by adjusting the final lock to open up the way into that area, where the last sealed chamber is protected by a strong guard. Beat the guard and enter the room to snag the last seed.

The Crystal Of Gluttony & Ring Of Gluttony

After acquiring all three Will Seeds they'll combine into the Crystal of Gluttony, which casts Marakukaja on the party automatically at the start of battle as long as someone has it equipped in the starting lineup. This boosts the team's defense and can help the Phantom Thieves weather some tougher attacks.

After defeating Kaneshiro the Crystal can be taken to Jose in Mementos to create the Ring of Gluttony, which automatically casts Tetrakarn and Makarakarn on the equipped character at the start of a fight, allowing them to reflect one physical and magical attack. It also gives them the ability to cast "Vault Guardian", a spell that functions identically to Marakukaja and costs 20 SP.

Persona 5 Royal is available for PS4, PS5, Xbox Series X/S, PC, and Nintendo Switch.
