Scripting difficulty - Damage detection and the like

[Devalut]

Hi I've recently gone back into skyrim and I've always wanted to get a damage absorbing spell that essentially extends the caster's life by X amount; however, I've been stumped to find almost none exist, or hide under names I have not seen.

For those who've never played starcraft, "provides an additional health bar that must be destroyed before the target will take any damage."

So my question is towards scripting difficulty, and whether or not I should bother in the first place.

The aspects would be
- a variable that can be based off of stats like a skill or magicka amount.
- it blocks all forms of damage or certain types (i.e. magic/ranged/melee)
- if the incoming damage exceeds the targets health but not the shield they will not die
- if the incoming damage exceeds the targets shield but not their health the damage will simply be subtracted from the remaining shield
