After a long wait and much anticipation, I made sure to spend enough new money to get the Miner's Helmet reward. Once received, I happily wore it mining. But I have recently noticed that I no longer receive the Armor Set Bonus while I'm wearing it. Taking a closer look, the helmet indicates Plate, not Universal as I expected. Because I wear chainmail, I'm losing the Armor Set Bonus. So, my helmet is adorning a chest and I'm back to casting the light spell while I'm mining. Must I really wear plate armor to go mining to avoid losing the armor set bonus? Couldn't this be universal?
