The toolset just aims to be better than gold in every way, it's faster, more durable, and even able to craft totems of undying!
A Helmet of Undying was also added, it has no function yet other than a cooler looking Palladium Helmet, but I will add that in a future update!
To craft the Totem of Undying, you need 5 Palladium Ingots and 2 Emeralds, you can guess how the crafting recipe will go from there. And to craft the Helmet of Undying, you need to put a Palladium Helmet and a Totem of Undying in a Smithing Table.
