For some reason the Falconry (Falcon Strikes) skill doesn’t create or consume flow stacks (Bladesinger Passive) when it is clearly a unique skill. The Falcon may be the one doing the attacks, but you are the one using the skill. I suppose this could be by design since Dive Bomb doesn’t work either, but it seems like a bug since Aerial Assault works. Either way I was deeply disappointed after putting this into practice and discovering it doesn’t work. The synergy seemed perfect, as if it was made to go together with cinder strike and the bladesinger passives. The three different strikes of Cinderstrike getting up to three stacks and then falconry consuming them.
