This evening it is planned to give the Legend Difficultly Sundial a go. I've been trying to this question in the title. I just want to double check.

Right now, the Sundial Boss is Tazaroc, the Sun Eater. The triumph states "Defeat Inotam, Oblivion's Triune, on Legend difficulty or higher."

Is the Sundial Legendary Boss the same as Normal Difficulty? Or to put it another way, does the Legend difficulty always have Inotam?

Just making sure there isn't an unpleasant surprise. I can already hear Zero. :P
