I've been trying to get it for a long while now and I've managed to kill a little bit over 1000 chaos elementals and still haven't gotten it till now. I cleared the whole area around the farm so nothing spawns outside and I even used greater luck potions I grinded for earlier in the playthrough. Is there something I'm missing? Anything I'm not currently using in order to make the process faster?
Here are all the buffs/things I'm using
Gnome statues
Water candles
Battle potions
Greater Luck potions
Four leaf clover
Bundle of Horseshoe balloons
Biome torches
Jungle biome
Galaxy Pearl
Shimmering a platinum coin for maxed luck buffs
High skies buff
