[1.2.172] The Knights of Cygnus - Striker

I'm unsure. It's kind of vague.

The way that the data is presented leads me to believe that it's like chain lightning, but can only attack three mobs. Yet I'm also lead to believe that it's a buff because it has a skill timer on it. So...?

I honestly have no clue on this one. I guess we'll have to wait for videos.

Using those numbers, my bet is that the summon uses that attack instead of the normal one, during that time, automatically, with you attacking meanwhile.
