Munchkin AT: What bonuses are doubled by Glasses of Nerdicon?

[vaughnerich]

"Glasses of Nerdicon." One shot items you play in combat have double the combat bonus. Does this mean it's only doubled if you play them to increase your own power level? (So one shots to enhance monsters are not affected?") Or does it mean only one shots played by people in combat?

[MunchkinMan]

Any one-shot Item that offers a combat bonus, regardless of side, will get doubled when played to a combat by the owner of Glasses of Nerdicon.
