Third Eye (サードアイ, Saadoai)? is an ability in Persona 5 that allows the protagonist to look for clues and items in the Palace. It is gained automatically early in the story, when the Fool Confidant with Igor proceeds towards Rank 2, when Kamoshida's Palace Treasure Route is secured.
It can be activated at will in the dungeon and highlights areas of interest.
- Stealable items gain a yellow glow.
- Interactable places like gaps and ledges have exclamation marks over them.
- Overworld shadows gain a glowing outline that changes based on their level relative to the party. Higher levels gain a red outline, the same level gains a yellow one and lower level encounters glow with a blue color.
In the real world, Third Eye can be used to examine on-screen locations that can be used for daily activities (NPCs, shops, Confidants and Velvet Room locations).
Reading certain books also allows the protagonist to use Third Eye during certain activities. In the batting cages, Third Eye causes time to slow from his perspective, letting them line up a better-timed shot. At the fishing pond, the Third Eye highlights fish, with different breeds glowing in different colors, allowing to gun for specific ones, like the Guardian.
