With Mithril not actually available right now (yes, despite its inclusion in various recipes), adamantite is Hytale's strongest ore. You'll need it, alongside cindercloth scraps, to craft top-tier adamantite weapons, armour, and tools, so don't expect to find it early on in your time in Orbis.
Adamantite is a rare, mid- to end-game material, and with that comes a pretty annoying and dangerous search. Don't worry though, I'll let you know where to look for adamantite ore so you can skip to the best bit: Smelting the ore into ingots and making powerful items.
