In every character's page there is a skills section. Under the skills section there is skill, ability, and chain.

The first two are self explanatory, but I can't figure out chain.

Let's take for instance, Agdala. Her chain is called Black Sword Master and it has a cost of 4.

How do I get Black Sword Master? How will I know when I get it?

What is the cost? Is that an additional character cost?
