This is the first time I'm doing the quest, so please don't spoil anything for me

I'm playing a level 3 cleric type of character with nothing fancy in my inventory. Just an iron mace and a shiny new set of steel armor I got from Balgruuf. Level three certainly isn't much for a deadra quest (I suppose), it's been tough but possible. Shortly after my dreaming journey, Erandur and I stumble upon a single orc with a two handed axe.
This guy just crushes everything. My summoned wolf dies within one hit, Erandur is quickly knocked out and I simply stand no chance. Since I only have one stamina potion, I can just shield bash him for two, maybe three times so Erandur can use his flame spells which do almost no harm.
Any ideas? This guy is like a rock.
