Final Fantasy Hacktics

Anyone had any success or know any ASMs to do something similar to a golem effect?

For an example: cast a spell on a target that absorbs up to MA*coefficient damage the next time they take damage...without it being party wide and not having the little golem pop up every time it blocks damage.

Would be interesting if certain classes could have a small self-absorb or a healer with a targeted absorb to block incoming damage.  Would be even cooler if you could make them specific to certain schools of magic.  The mechanics exist in the game, just not sure how to manipulate them.
