MM3 - I MISSED Marine's Heal Spell !!!

I didn't check the pillar in the first cave so I didn't get Marine's heal spell!
I am about 2 hrs into MM3, almost thru the Orc Cave...so I 'could' - I suppose - start again....
(which in my mind would be worth it so Marine has heal the whole MM3, right?)
UNLESS:
IS THERE another way/place to get it?
Does she learn it at a certain level as in MM2?
Thanks,
