Players can obtain weird pictos in Clair Obscur: Expedition 33 by trading a token with Tom before starting their journey to the continent. To utilize these pictos, players must reach Gestral Village, where they can interact with the merchant Jujubree in the bazaar. Jujubree will examine the weird pictos in the player's inventory, potentially leading to significant upgrades, such as enhancing an Augmented Aim picto from level two to level five. Players are encouraged to return to Jujubree with any additional weird pictos they find for further enhancements.
