Composure defines ones ability to keep cool in stressful or intimidating situations, and how good they are at keeping others in check as well.

A low Composure character however is quick to nervous breakdowns at the slightest intimidations, and are prone to triggering it in others as well. The effects of hysteria can result in penalties to all Skillchecks, inability to listen to anyone, lowered AC and increased damage taken, or even a catatonic state in which they're unable to act at all. High Composure characters can keep calm and stay stoic or brave during the most frightening encounters, and bolster the courage within their teammates as well.
