Restoration seems to be leveling slowly using health spells and ward spells, are there any spells that can make it level faster?

the spell Circle of Protection leveled me up fast.

got from 75 to 100 in a short time

I saw one guy post on here once to equip a weak damage spell in one hand and a healing in the other. Then find something that's not a threat to you (wolf, bear, etc) and dual cast on them. You'll damage them and heal them at the same time.

Me just regularly using restoration all the time instead of health potions has my level going up at a steady rate all on its own, but if you don't want to tangle with animals that could kill you like t.adams suggested find a blacksmiths forge and keep running around in it/jumping in and out of it to damage yourself and then heal yourself.

Mudcrabs. Let one attack you while you heal. Circle around it until MP are restored. Rinse and repeat. You'll level your armor also as a nice bonus.

This also works great for getting your block skill up for those that never raised that up, those mud crabs may go down with one hit but the deal out some hard hits!
