If you are pre-hardmode, you will make the lihzahrd bricks into any building material, high tier preferred, like obsidian or obsidian bricks. this is so you can fight bosses, around it, and near it without destroying the farm, or grinder. If you are in hardmode, I would suggest that you wore beetle, or Tiki armor, because they attract enemy's also, if you are in hardmode, or pre-hardmode, at this point you need to put down water candles! they will attract more mobs to come and be killed by your dart traps. if you want, you can put a long line of crimson, (corruption will NOT work) off to the side, then it attracts the crimson mobs too, this can also be done with the hallow, as seen in the picture below.
