The wearer cannot become affected by the Diseased condition. This item does not prevent Disease-based HP damage, only the Diseased condition.
Diseased Condition: Disease can deal HP damage (though not always), but if you fail a saving throw for Disease, under certain conditions, there may be repercussions. Simply taking Disease damage won’t trigger this condition. It must be the result of a special attack that causes this condition and you must fail the save.
