Aiming:
As an action, the shooter may take time to aim. This will increase the attack die type by one step on the die chain and increases the damage to two dice.
If the shooter has multiple action die, they must use their first action die to aim. (i.e. If they have two action die, 1d20 & 1d16, their attack will be using the 1d16. Since aiming improves the attack die by one step, their attack will be with a 1d20. If they have two (or more) 1d20 attack die, their aimed attack will be with a 1d24.)
If the shooter has only one action die, they must spend one round aiming and attack the next round. If their aim is interrupted by an attack on their person, the aim has no effect.
Range:
Short range and below has a +2 modifier
Between Short and Medium range, there is no modifier
Between Medium and Long range, the attack die is one lower than normal (1d16 instead of 1d20, 1d14 instead of 1d16, etc.)
