I have a few questions:

- Does Magicka Absorption also negate damage?
- How do they stack up?
- What happens when you have a 50% resistance and someone casts a 100dmg fire spell on you:
(1) You take 50dmg 100% of the time.
(2) There is a 50/50 chance that you will take 0 or 100dmg.

It's a constant reduction.

For magicka resistance, my understanding is 1, this would be like past games.

For absorption, I think it's different this time. I think it doesn't mitigate damage, it just gives you back mana. And again this time (unlike before), 30% spell absorption means absorbing 30% of the magicka, not a 30% chance to absorb the whole spell.

No clue on stacking.

Resist - Reduces shock, frost, fire, magicka, the damage afflicted by a normal weapon or reduces the chance of being poisoned, paralyzed, or diseased.

Resist Magic always works, and reduces the effectiveness of the incoming spell by a certain percentage.

From - http://elderscrolls.wikia.com/wiki/Spells
and - http://www.uesp.net/wiki/Oblivion:Magical_Effects#Reflect_vs._Absorb_vs._Resist

Spell Absorption is an M% chance to convert all of the energy from a magical effect into your Magicka points and avoid its potentially damaging effect. For example, if you had 50% Spell Absorption, half of all spells (on average) cast at you would simply refill your Magicka, depending on the strength of the spell, instead of otherwise affecting you.

Absorb attempts to convert incoming magic into magicka for the target: its magnitude is the percentage chance that it will succeed. If it does, all of the incoming effect is negated, and the target with Absorb on it receives magicka proportional to the magnitude of the incoming spell

From - http://www.uesp.net/wiki/Oblivion:Spell_Absorption

Restance to poison, paralyze and disease causes a "chance" scenario, but any other spell / damage causes a percentage to be taken off of the damage.
E.g 5 frost resist on a frost touch spell that does 100 damage = 95 damage.

I'm not entirely sure how it is calculated, but it is not 0 or 100 damage it takes a percent off of the original damage.

I'm almost positive spell sbosrption does NOT work as posted above. Those wikis are terribly (and understandably) incorrect at the moment on many if not most things magic.

For example, look at the Atronach perk description: "Absorb 30% of the magicka of any spells that hit you." ANY spells that hit you suggests this is not the % chance to absorb everything.

Thanks everyone

So, there is no definitive information if spell absorption also negates damage?

That's Oblivion data.
