Immunity to debuffs?

Shield of Trust having immunity to debuffs is the first I'm hearing that, since threads talking about SoT in KR not once ever mention such a feature. Nexon's pretty infamous for their excessive typos, outright stating incorrect information (e.g. Way of the Gun description says all dual gun attacks are criticals when it's only normal attack), mistranslations/misinterpretations (e.g. they say Judgment Blade reduces Apostle Defense when it ignores it instead), and/or throwing things out of the blue (e.g. Luck Evasion formula), so it's hard to trust them.

I'm not saying they're wrong this time though.
