I know there is the wizards hat and gem robes, but are there any accompanying boots/pants?

Farmed over 100 undead miners for the mining pants and still no luck. I’ve had multiple helmets and shirts but the pants (which are the only thing I need to complete the knight in shining armours trophy) just will not drop. Honestly why is it so ungodly difficult? I’d never even wear the armour even if I was mining because of how low the defence is, and it’s just completely ground my achievement hunting to a halt. I’m spending multiple hours just sitting around with battle potions and water candles in the cavern layer in a big ol arena, waiting to see the light from their helmets. When I eventually see one my hopes are immediately dashed by the bombs that it inevitably drops.
