sadly, I don't have Mars or Ama so.... I'm only using Heph when i need the Ex slot for something else...
in fact, all my fire SSR (Ares, Acala, Svarog, and Dakki) are all offense without the debuffing...
ugh, don't remind me.... although it could possibly be longer since nutaku isn't DMM and already deviated a bit (like the SSR gacha)
