Stones and runes

Special stones

Stones are the third layer of gear. A stone has a kind and a tier (I to V); drag it onto gear with a free socket to set it (one stone of a kind per item). Diamond gear has 1 socket per piece, netherite 2. Stone Dust raises a socketed stone one tier (1 for tier II, 2 for tier III, 6 for tier IV, 15 for tier V). The Arcane Extractor (/extract) takes a stone out for $4,000 or reforges it into another kind of the same tier for $25,000 and 2 dust. /stones lists every kind.

The Rune Forge

/runes sells runes, relics and wards for Aether Crystals, which are earned only by fighting (mob arena waves, world bosses and champion and legendary elites). Nothing in the forge can be sold back. Attuned runes are bought once, upgraded level by level and attuned: one rune each in the Offense, Defense and Utility slots and one relic in the Relic slot.
