As Lolz stated, pre patch sceptres had potential for that, but I was told they cut back base damage and upgrade damage to ensure a more balanced weapon. I have seen around 400-500 upgrade Ultimate++ scepters capable of reaching 60-70k towards the top end, which is now what the "best you can get" would be for your interest. My own is around 480^~ reaching only 67k for comparison. Good luck in your search (lets farm Masuary :D ) The damage on Ember Scepter has never been changed the damage number was halved on the weapon but a 100k Ember Scepter last patch witch would heaved turned into a 50k does the same damage as before when it was 100k just the number it displays has changed to match all other staffs in the game that change has also been done to the Fusion Rift and Elder Staff. So Simply the Ember Scepter Damage has never been touched.
