Beyond the usual, the only special ability that seemed to be attributed to Gungnir was that regardless of the skill and strength of the wielder, it would always hit the target.

Beyond that, it seems to usually be the generic (Odin flavor?) divine power, fire, lightning, or some other kind of energy blast.

Not the easiest source material.
