Liam's Glasses

Liam's glasses are a piece of eyewear in Fallout 4.

Characteristics
Liam's glasses provide a bonus of +2 to Intelligence while incurring a penalty of -1 to Charisma.

Locations
From the quest plugging a Leak given by Justin Ayo at the Institute, available after Mankind - Redefined. You must side with Liam in framing Justin, and pass the speech check for additional rewards to obtain the Glasses. Be aware that this quest will be unavailable if you have completed Tradecraft, which is an early quest, making these easily missed.

Bugs
On the item card, the Charisma -1 is improperly displayed as Charisma +1.
