Check Resources, to see what you must harvest before you can craft anything.
RINGS
Rings are equipment that go into the left or right ring equipment slot.
They are part of the accessories family.
Currently, Silver rings tend to have more tempo while gold rings seem to have more critical chance, although they almost always possess boosts to both stats.
AMULETS
Amulets are equipment that go into the neck equipment slot.
They are part of the accessories family. Along with having varying stat boosts for your character, they are also the only accessories item which directly affects your character model. That is to say: You can show off your amulets but not your rings.
They provide a small boost to tempo and crit chance most of the time and will not be craftable until you find a formula.
PRECIOUS STONES
Players can find four types of precious stones when mining in caves. They’re used to craft higher tiers of equipment.
Emerald Nuggets
Emerald Nuggets are found in caves, and are used in crafting gear with green names. Items with green names have increased rarity, and therefore have better attributes.
Sapphire Nuggets

Ruby Nuggets
