Collect & craft
Pick a goal, then spend Knowledge step by step — trees open on demand.
Crafting stat boosts for all JC recipes: Multicraft, Resourcefulness, and Ingenuity.
Gemcutting for all four gem colors. Each color has a root node and sub-specs that unlock Flawless gem recipes and Prisms.
Rings, necklaces, and profession accessories for JC, Enchanting, and Inscription.
Tradeable reagents, plus Prospecting (ore into gems) and Crushing (gems into Glimmering Gemdust).
Spend Knowledge in this order. Open trees only when you need a visual.
