I've been playing with this for a while now and have literally never seen it proc a single time. Is there some trick to make it function that I'm missing beyond having the T4 Ability and putting your regular Bardic Inspiration on another character? Does it perhaps lack visuals?

I was hoping it proc'd at the same 20% that Stormsinger C2 claims to have AND that it also applied your other core upgrades and debuffs, particularly C5's "Whenever your Lightning Strike goes off, the enemy is Frozen with no save for 3 seconds."
