I can't see anything even close to 3% ssr rate on Nutaku every time I do 100+ rolls on 2 accs. Only 11 ssr hime, 0 boosted (Cybele u, Seth, Arianrod, Vohu - I failed all of them) + 7 or 8 eydo during 14 months. If my calculation is correct it's less then 2% rate in my case. Well, quality of those hime is much less because low boost rate too, but on 8 or 9 month old DMM acc i already have more ssr (especialy water team of Vohu Lakshmi Asherath Ruy-Oh, Saraswati in reserve with 0$ spent. Fire ulti is easy doable on AAB with 5 sr disasters in grid).
