Temper is how one acts upon being filled with an anger or rage.
Characters with a low Temper score will often have outbursts when provoked, resulting in reckless behavior, lowered AC, increased Strength, non-existant Perception, or triggering mania, anger, sadness, and distraction in others. In this state, character's in a full blown outrage often do anything but fight without abandon, attack their surrounding environment, or get lost in arguments. Higher score Temper characters can calm themselves and anyone else soon to snap.
