When a unit with 1 or more weapons that have the Long Shot keyword makes an attack, before choosing an enemy unit to attack during the Declare Defender step, it may spend 1 Aim token to increase the maximum Range of each weapon with the Longshot keyword by 1 until the end of that attack sequence. The attacking unit may not reroll dice with any Aim tokens spent in this way. Only 1 Aim token may be spent in this way per attack sequence.
