Enchanting and Soulcrafting

Enchanting increases an item's base stats. When an item has been successfully enchanted, the item's name will change. For example, a Bronze Sword that has been successfully enchanted once from its base state will be displayed at Bronze Sword+1. An item can be enchanted up to a maximum of 15 times, but is limited on its weapon level. The higher level of Enchantment attempted, the harder it will be to succeed.

Soulcrafting imbues the item with Soul Force that increases the grade of the item. Each grade increases the strength and value of the item. There are five possible grades for items:
Regular
Advanced
Special
Artifact
Legendary
