healing is good, it's already available to Ment.

Well, my healing, you need to understand, is either after a battle or for the same front-line units. If a mage or archer gets injured, I seriously doubt I'll be able to run around the entire battlefield and heal them with my speed.
This is to say that insurance won't be unnecessary.

I choose immunity to bleeding and go to learn from Eisen.

And yes, wait with the immunity for now, seriously. If you're going to befriend Eisen, he has a 50% chance to remove negative effects at the beginning of his turn, so bleeding won't be super dangerous then.
