How to activate Battle Art Chains?

[iLiberate]

What is this and how do I accomplish it? Thank you!

Have an NPC officer use a battle art when you do. You'll see a blue line connecting you to a nearby officer. Use a battle art when you see that.

If a blue line is connected between you and an enemy, it means use your soldiers to attack them with a tactic.

Can it be any officer? I’ve never seen this outside musou before

It can be any officer, even generic Brave / Wise Generals for example.

You may see the blue line more often when you rescue an officer, parry, perfect evade, score enough KOs, and defeat enemy officers.

allied officers or companions.

make sure they're near by to see you do perfect evades or parry or defeat enemy officers etc. you'll see a blue line between you and then. once you use an art, they'll follow it up.

its harder to do and might take a long time to impress them.
there's an equipment item that make it easier. i forget how i got it

It's not just a blue line. Your battle arts will be blue too. It's RNG dependent.
