Rulings:

• 9/15/2013 You divide the damage as you cast the spell, not as it resolves. Each target must be assigned at least 1 damage.
• 9/15/2013 If some but not all of Boulderfall’s targets become illegal, you can’t change the division of damage. Damage that would have been dealt to illegal targets simply isn’t dealt.
• 9/15/2013 If an effect creates a copy of Boulderfall, the division of damage and number of targets can’t be changed. The effect that creates the copy may allow you to change targets, however.
