i dunno if this will work for you, but I find a lot of the time in terraria, I can kill a mob, leave that spot a bit, like offscreen and move back and that mob comes again. It worked a lot for the dungeon slime, i got so many keys that way. I have also used this trick to get ice golems to keep coming.
