Golurk (Ancient Origins 35) and Superpower: Is Resistance Applied to Self-Damage?

[galaspark]

This Golurk has an ability that makes it both Psychic and Fighting type. When it uses Superpower, and does 20 damage to itself, is the resistance from being Fighting type applied to its self-damage, making the self-damage zero damage? I wasn't 100% sure if self-damage applied Weakness and Resistance either (I couldn't find a statement in the Compendium that self-damage applied Weakness or Resistance.)

You'd probably find a ruling in the original Compendium. It used to come up more often.

This ruling is in the FAQ for the set.
W&R does apply to self damage, if it is damage and not placing damage counters.
In this case, as long as Golurk's Ability is active, it is Fighting type and the Fighting Resistance will apply.
