Darkhawk boss 7.4.1 with tigra

So this boss has nodes that allow champs to gain prowess. I didn't have a problem with my other champs getting prowess, but when I went with tigra, she had trouble building prowess. I managed to get only 1 the entire fight. Is there an interaction with tigra's abilities or darkhawk that limits the prowess buildup?

Her neutralize reduces the node's ability accuracy
