Ah I'd never use anything besides my Malice on the Daughters & Oryx. Infinite ammo, double the damage, really can't beat it. It's fantastic lol. I wouldn't imagine telesto being great on oryx though. It's really important to have that instantaneous DPS when he opens his chest so he doesn't wipe you. Maybe it would work, it is a very powerful weapon. But I wouldn't suggest anyone use it over a sniper rifle or touch of malice for Oryx or Daughters especially. Also considering you're a pretty good distance away from Oryx, I wouldn't think fusion rifles in general would be an effective weapon choice. Maybe though, it does surprise every now & again how much health it takes out of some enemies I hit. lol. Regardless of the raid though, one of my favorite weapons in destiny. & not to mention the way it looks...is friggin sweet
