Heh, yes, instead of fighting yourself you could let creatures fight for you.
If you have choosen to become an innocent healer-type character you will get problems defending yourself, so you could either get an animal companion who follows you, or you could summon creatures who under a short time fights under your command (or individually) against foes (like the Aeons from ffX).
These would protect you, and in return you give them your love, friendship and care.
The summoned creatures doesn\'t have their own will since they are created by you, and can as well be unsummoned by you.
I like the idea about creatures who shares a bond with you. The closer they are to you the less is the chance they flee when hurted. The creature could have a meter that shows how strong the bond between you and your companion is.
A full bond means they protects you with their life.
There should be some things that strengthens your bond, like if you heal your companion a lot, gives it food, protects it when it\'s defenceless, plays with it a lot etc.
The creature could also be able gain levels so it becomes stronger and gets special abilities, like if your companion is a bird-like creature it could be so strong it can lift you and give you a ride.
Permanent death of creatures could bring some drama into the game
