To create Awakening items you will need:
A sealed item specifically for your class, the item will indicate which class it is worn by.
Next you need to find the chaos goblin (Lorencia 142x115 or Noria 179x102), open it and click Regular Combination
and insert the item you need here along with Ancient Hero's Soul
Unsealing an item has a 100% chance and the item does not burn, and you will receive an Awakening item
