Entropic warding

Entropic warding is a defensive warlock invocation designed to deflect ranged attacks.

Effect
Entropic warding appears to be a combination of the spells entropic shield and pass without trace.

The warlock is surrounded by chaotic energies that deflect incoming projectiles, rays, thrown weapons, etc. He also leaves no trail, and cannot be tracked by his scent. (He can, however, still be detected by scent.)
