Now that's odd, because Rallicus on the previous page states he's done something similar to this and found it was a cakewalk.
I'm wondering if he only did certain quests or otherwise optimised his gameplay as with his self imposed limitations, I can think of several enemies that would fry him very quickly (Otar the dragon priest for starters - the only boss that killed me multiple times, or any high level mage with slowing frost).
