If no other treasure-enhancing tokens (regardless of rarity or permanence) are equipped, the player receives one additional Treasure Chip at the end of the adventure.
If a variable-effect token is being used to gain Treasure Chips, Lenses of Fortune will not stack with it. E.g., if the Amulet of Wonder‘s effect for that year increases Treasure Chips gained, Lenses of Fortune and Amulet of Wonder can’t be equipped by the same character.
