Bladed dash:
When you cast this spell, you immediately move up to 30 feet in a straight line any direction, momentarily leaving a multi-hued cascade of images behind you. This movement does not provoke attacks of opportunity. You may make a single melee attack at your highest base attack bonus against any one creature you are adjacent to at any point along this 30 feet. You gain a circumstance bonus on your attack roll equal to your Intelligence or Charisma modifier, whichever is higher. You must end the bonus movement granted by this spell in an unoccupied square. If no such space is available along the trajectory, the spell fails. Despite the name, the spell works with any melee weapon.
There are all sorts of things that have me unsure about it. What do you guys think?
Key points:
* You need to be adjacent to the creature at some point in your movement.
* You can attack at any point during the movement.
* The spell works with any melee weapon.
A reach weapon is a melee weapon. No problem there.
It doesn't say that you must attack while adjacent.
There are times where it wouldn't work, but most of the time I would expect you could find a path that meets the requirements.
What I really wish it said was that "You can make an attack against any opponent that you could attack from any position along the dash" because my mindblade magus has greater bladed dash and would love to cut a swathe through every enemy within 10 feet, but alas.
It is good to know, though, that wielding a reach weapon doesn't break the spell's normal function.
