The currency of the continent. Every Yang pile you pick up funds upgrades, potions and gear from the shops.
vnum
The number the game calls every item and monster by. Sword+0 is vnum 10; the same number appears in drop tables, shop stock and quest rewards.
Upgrade (+0→+9)
Armour and weapons improve from +0 to +9 at the blacksmith. Each step has a yang cost, a success chance and — from +6 on most armour — a material list. The upgrade math guide walks a full chain, and the upgrade simulator runs any chain for you. See it end to end on Iron Plate Armour.
The extra stats an item rolls when it drops or is upgraded — max HP, attack speed, critical chance. The pool of possible applies lives in the bonus reroll calculator; try rolling one onto Wooden Bracelet.
Rare bonuses
A second, rarer apply line that high items can carry alongside the normal one. The bonus reroll calculator separates the rare pool so you can see what it can roll.
Metin stone
Falling stones that anchor the meteors\' influence — destroy one for loot, experience and a kingdom quest hook. They start with the Metin of Sorrow on the first maps and climb to level 105 across the stone layer of the world map. The Metin hunting guide lists them level by level.
The class researcher who collects monster parts for permanent bonuses. The collection quests start early — gather herbs for the level-4 herb delivery, then hunt for the level-30 biologist quest and beyond.
Dragon Soul Alchemy
The diamond alchemy that runs on its own equipment pane beside your armour. Its pieces — like the Rough Dragon Diamond family — refine through their own table rather than the blacksmith\'s.
Spirit stones & sockets
Equipment with sockets accepts spirit stones, each stone adding one bonus. A socketed shield such as Battle Shield shows how the mechanic attaches to gear.
Empire change
Switching kingdoms mid-journey costs yang and resets your standing — the empire change quest carries the conditions.
