well, maybe just to summarise what i've tested out so far with shield of heaven :

(1) the shield absorbs ALL kind of attacks, including magic, gun and physical. they might appear as "blocked" on the screen, but they are absorbed and the shield's HP decreases.
(2) the shield's HP cannot be replenished through healing skills. it can however, still regenerate its HP over time or recast to get it back to full HP.
(3) once its HP is finished, the shield disappears even before the duration time is over.
(4) if the shield has xx amount of HP left, and someone hits more than xx amount of damage, the shield disappears but the user does not get any HP decrease.
(5) the amount of HP of the shield depends on the user's total MA.

i hope this clears up the idea of Shield of Heaven. pls do tell me if i missed anything or wrote something wrong.
