Unless I missed something in my quick read through to refresh my memory, you don't do an attack roll for a damaging creation spell.  
You can attack with one, I mean if you make a sword or something, but that's just a normal attack roll.  Not an attack with a creation spell.  And if you create something that causes damage when they touch it (fire, lava, whatever), it's not an attack roll there either.  Again, unless I missed something in that read through.
The range of the spell is it's range.  Not a range increment.  If it doesn't say range increment, it's always, as far as I've seen, just a range.
Compel and Enchant spells don't cause damage.  Not by themselves.
