How can I increase spawn rate of mining armor/undead miner?

I'm having trouble with finding the mining armor set dropped from the undead miner.
undead miner<---- This guy

The pants and shirt have a 2.4% dropping rate.
I already bought the helmet from the merchant.

What have I tried?

I have explored the underground for an hour with battle potions on but I have encountered the undead miner 2 times now. I think this could be faster.

Solution 1:

My suggestion for increasing the number of miners you encounter is to simply increase the number of total monsters you encounter. Try using the following:

  1. create 1 large open cavern underground. This increases the likelihood they will spawn in an area where they can run to you. If you do not do this, there is a good chance they will spawn in a pocket not reachable to you (they still count as being spawned on screen and will reduce the amount of enemies you find).

  2. If you can, play multi-player. The spawn rate and maximum number of enemies allowed on screen is directly proportional to the number of players.

  3. Use battle potions. These increase the number of monsters that will spawn

  4. use Water candles. Place them around your large cavern. Being close to them will increase the spawn rate of monsters. You can also hold 1 in your hand, this will futher increase the number of enemies that spawn.
