Upgradable and non-upgradable gear

Non-upgradable. Quality is set by the level of the materials: secondary, common, uncommon, rare, epic, legendary. Higher quality means larger bonus percentages and better stones the item can hold. • Secondary — 1 secondary-quality stone • Common — 1 common or secondary stone • Uncommon — 2 stones up to uncommon • Rare — 2 stones up to rare • Epic — 3 stones up to epic • Legendary — 3 stones of any quality plus 1 rune of any quality Stones in one item must not repeat by type. Upgradable. Split into craftable and obtainable. Obtainable ones — from in-game events, for in-game currency, or won — exist only in legendary quality. Craftable ones can be made in any quality, but only legendary can be upgraded. Any upgradable legendary item goes up to level 15 for materials and Helheim Fire, which drops in the Helheim basement. • Level 12 unlocks a fourth stone • Level 15 adds another rune Runes, unlike stones, may repeat: two identical runes are allowed.
