Catalyst and essences
Quality is rolled, not bought. The catalyst is the one exception: it fuses two identical items to climb one tier, in exchange for perfect prisms.
In short
Two items of one tier, one item of the next.
A fusion takes 2 identical tools, same name and same quality, and returns a single one, one tier higher. No tier is ever skipped. You choose the kept tool: it keeps its id, its modifiers and its enchantments, and takes the highest temper of the two.
Each fusion costs perfect prisms, based on the tier reached: 2 to uncommon, 5 to rare, 15 to epic, 40 to legendary.
Going from 16 common tools to one legendary takes 15 fusions and 106 prisms in total. A legendary is earned.
An essence carries a rarity, and nothing else. Applied to a tool (>catalyst apply), it sets the tool's quality to that rarity, guaranteed, without touching temper, modifiers or enchantments. Two essences of the same rarity also fuse into one of the next rarity, for the same prism price.
Essences drop from enemies in the Depths (>dungeon), more valuable in the Forge and the Void, and sometimes arrive by mail.
A tool's net worth follows its quality: it is multiplied by 1.5 at uncommon, 2.5 at rare, 4 at epic and 6 at legendary, then its enchantments and modifiers are added on top.
Tool fusion

An equipped, frozen, favorite, broken or NPC-held tool cannot be fused. Remove the protection first.
