Not sure about that, couldn't test with edo hiruzen, but i run a test with sai (have same 5 elemental passive) more on it in this thread

maybe if someone who upgraded the assist a few more % can confirm it as i could only test on initial 2%.
Pretty sure it doesn't work on Edo Hiruzen. Tested with Fu and Ao. Fu produced more damage for Hiruzen against the Kakashi clones (in my case, about 12k per standard attack hit). In comparison, Ao produced slightly lesser damage (in my case, around 11k per standard attack hit) for Hiruzen against the Kakashi clones.
