anon this was with foumes.
pretty much any damage mod is going to push it over. For example you could use flyer or just a non-mlb grail and be perfectly fine. Hell, I could probably use the 40% arts snake CE.
or, like mentioned, at 6ce with an MLB ce on caster artoria just have her NP on wave 3 and the 30% atk and extra overcharge should be more than enough.
