When you have Dancing Shadows in Dive bomb skilled, your direct falcon makes zero damage when you have active shadows.
In this video you can see how I first, without a point in Dancing Shadows, cast smoke bomb and wait for shadows to appear. I then cast Dive Bomb on the training dummy outside of the smoke cloud, and it takes damage like normally (I do this two times):
Then I spec a point into Dancing Shadows and repeat the procedure twice. Both times, my direct Dive Bomb cast on the dummy makes zero damage. The same I notice with normal enemies in quest echos.
Does not make any sense to me…
