Looking for a specific ranged feat...

[RigaMortus2]

Is there a feat (or perhaps spell/power) that allows you to change the angle of a missile weapon? I thought there was a psionic feat (or power) that allowed you to change an arrows direction by 90 degrees, so you could (for example) shoot around corners and what not. Maybe I am just making it up...

The Arcane Archer has a Seeker Arrow spell-like ability that allows the class to do this. I'm not sure of there are 'seeking' arrows as well. Complete Warrior has a Blood Seeking weapon ability that works like this. It's a +1 ability.
