I would say St.Pat’s feet for mining and Demeter Cornucopia for farming. :D
Ponk Pick 100%
Helps you get mythical rares from every single outside chest beyond 1000 blocks from the exit, would definitely add next map and totally balanced.
Gaia Pick all the way, that thing rips through blocks like a hot knife through butter.
Plunder wand or Zeus bolt made outside way more fun.
Definitely Tophat, I got my first tophat and sold it for hydra pick, flower and 2 billion dollars. A few weeks later someone offered me another tophat for a pvp set and flower.
This item is my fav because it has so many possibilities from afk farming to mining with extra gear or pvping while using Zeus legs + Zeus tempest guaranteeing 6 hearts of true damage. It has so many other undiscovered combinations that probably will never be discovered due to how rare this item is.
