Hi :),

if you can find a Ring with Charm Quality (goes from 1 slot to max 5 slots), then you must learn the Skill Enchant Weapon (this name can be mis-understand, because NOT only weapons have charms slots wink ).
If you have 1 point in this Skill you can put max 1 Charm in some of your gear that have at least 1 (or more) charm slots. With each point in Enchant Weapon you can put the same amount of Charms in an item.

There're Charms of many kind and you have also from each kind weak and stronger Charms!
There're 5 levels, from low to high: Uru / Ser / Min / Pag / Yit.
There're Charms that boost your Vitality, Magic (Mana), Intelligence, Strength, Dexerity (Agility), Constituttion, all four Resistances.

Good luck ! wink
