It was for dragon chest scales, 10% chance for attacks to dispell a beneficial effect from the target.
Due to it being for dragon chest scales, it may have originally been planned for use in the Withered Scales event in April 2004 from which the other dragon chest techs came. But either it wasn't used, or never dropped for that event for anyone.
