Mirrage Archer (using High velocity round)

The following supporting gems:

Knockback
Elemental Armament III


doesnt seem to work despite being socketed in skill. I cant notice anything in skill tab of High velocity round.


Can anyone confirm if it works or the tooltip is broken please?

Indeed doesn't work. Also i tested Plasma blast with Mirage Archer and after dodging the miragge Char appears but not hitting enemies. Just stand and watch.

It's totally buged.
