Someone else doing it would be a nifty challenge for someone!
Also, there is usually a healing scroll on the right side of the map but you have to dig it up.
Maybe I just got super lucky but in my 2nd playthrough with a Mage, I still got it.
My 1st playthrough as a Viking/Warrior, I got about 4 Calls of Nature, and a lot of healing scrolls but... no way I could learn Order magic so it was a big trickier.
