Yeah, one way is:
I have a strategy for duegon, at night, make a house outside with bed (no this is not about defeating Skeletron), set spawn point there, make a chest, get torches, then run your faith through the duegon looting chests, no worries in dieing, simply put your loot (coins) in the chests and be happy, althrough when you die you indeed lose half coins, but it's mostly for the items in the duegon.
I got a bunch of items from doing this, including the Muramasa.
