You should use stardust dragon in that build instead. You can right click with the dragon staff to improve dragon's targeting range and hit stuff off screen.I'll admit, when I did Expert and Master Mode summoner, I did all Cell staff with Vortex Beater+Chlorophyte and just kept my distance the entire time (w/ Spooky armor so it still felt like summoner).
There's nothing wrong with mixing weapons from different classes, in fact the fastest kill time in my moonlrod tests invloved using spooky for a big dragon, supported by a phantasm phase 1, then switching to daybreak phase 2.
