A Path to Steam
±5 points per ±1 Per
Perception represents your general alertness. The GM makes a “Sense roll” against your Per to determine whether you notice something (see Sense Rolls, p. 358). By default, Per
equals IQ, but you can increase it for 5 points per +1, or reduce it for -5 points per -1. You cannot raise Per past 20, or lower it by more than 4, without GM permission.
