Sancho II of Portugal’s Ciborium

Origins
Pancho II was king of Portugal after his father died. Sancho was a capable military leader, but a poorly inefficient head of state, focusing all his time on campaigns against the Moors instead of political matters. He was taken out of power by the Pope and replaced with his brother.

Effects
Those who drink from it have all their attention and abilities focused on one activity. They will try to finish their task with their complete potential, ignoring breaks and other distractions. However, the person cannot cope with anything outside of their “field of focus”. They either shut themselves out from everything in the area or react violently when disturbed. Since they will continue working until their task is finished, they will ignore basic needs such as sleep and food, which poses a serious health risk.
