Forge Techniques and Advantages

Forge Techniques include the Advantages that blacksmiths can convert Properties into. The Blacksmith Core Skill allows you to choose two of the four basic Forge Techniques (Hard, Dense, Light/Flexible, and Conduit/Silver) and a third can be chosen each event if you purchase the Blacksmith Skill Versatile Technique. You can only choose a Legendary Advantage if you purchase the Blacksmith Skill Legendary Smith.  

Advantages

Advantages are similar to Skills and either confer On-Repair or Passive benefits but are tied to the item instead of the character which allows them to be used by anyone who is actively wielding the weapon or shield, or wearing the set of armor. Although most Advantages are either On-Repair or Passive, many Foundation and Legendary Advantages can only be used once per event or even once per season.  
On-Repair Advantages
These confer single-use abilities which function as independent Calls and cannot be combined with your normal attack or other Calls unless otherwise specified (such as the Puncturing Advantage). On-Repair Advantages can only be restored by a blacksmith who performs the Repair smithing process on the item.  
Passive Advantages
These confer a permanent benefit to you as long as you are actively wielding the weapon or shield, or wearing the set of armor.
