So, if I did 100 magic dmg to an enemy with `magic damage reduced by 10`, 50% magic resistance and 10% magic absorb, it would look like this, correct?
100 - 10 = 90
90 * .5 = 45
45 - (45 * 0.1) = 45 - (4.5) = 40.5 total damage dealt
If that's the case, does -magic resistance at say 200% double my paper doll dmg ignoring flat reductions and absorbs, or does it scale differently past 75% or 100%?
Since monsters do not appear to get the healing benefit of absorbs, your math is correct. If you had -199%EnemyMagicRes or more, then yes it would exactly double your skill's listed damage. Monsters appear to be capped at -100%Res, so if you ran into a non-immune monster then your -%EnemyRes gear would have full effect, and at 199% you would always bring them down to -100%.
The only diminishing returns is in how much you actually notice the benefit. For example (with 0%Resistance monster), if monsters take 100 hits to kill, then with -200%EnemyRes you'll kill them in 50 (probably really worthwhile), but if monsters took 3 hits to kill, then with -200%EnemyRes you'll kill them in 2 (probably not worthwhile). After around -80%EnemyRes (monsters are either completely immune to you, or your damage is at least 4/5 its total), you'll probably start noticing the benefits less and less, but -100% could still be worthwhile.
