A stone lifts one stat line on your gear by one rarity, and it never fails. Stones come in five tiers — the tier you use is the rarity the line ends up at.
💎 The five tiers
Common Enhancement Stone — only for merging: 5 make 1 Rare stone
Rare Enhancement Stone — lifts a Common line to Rare
Epic Enhancement Stone — lifts a Rare line to Epic
Legendary Enhancement Stone — lifts an Epic line to Legendary
Mystic Enhancement Stone — lifts a Legendary line to Mystic, the top rarity
🎯 Where they come from
Stone harvest — Common stones in the Forest, Rare stones in the Desert · after your daily quests
Prismhorn boss — Epic, Legendary or Mystic stone for the top 3 and the final blow
Recycling — an outfit or a mount → 2 or 3 stones, tier set by its stat lines
Market — Epic stones and up, bought from other players
🧑🔧 Two NPCs
Stonesmith — Merge Stones · Split Stone · Recycle Mount · Recycle Outfit
Blacksmith — the Enhance button, where stones get used
Every action costs 3,000 gold, at both of them.
