Description

Hi,
Could somebody explain the difference of elemental absorption in percent and in number ?
Like Ground runeword: 10-15 %
And

Blackhorn's Face: +20
What's the difference, which one's better ?
Thanks

Can be used to make Runewords:

If you take 400dmg from sg then with 75 res;

20 abs
(400*0,25)-(20+20)=60
you will take 60 dmg

15% abs
(400*0,25)-{<(400*0,25)*0,15>+<(400*0,25)*0,15>>}=70

with 85 res;

20 abs
(400*0,15)-(20+20)=20

15% abs
(400*0,15)-{<(400*0,15)*0,15>+<(400*0,15)*0,15>>}=42

however, if you ever take enormus dmg (from a single source), the % abs will become better.

What is also important is the order (if you have two kinds of absorb). First the resistance is applied, then fractional absorb, finally absolute absorb.
Amazon Basin has some nice examples:

Lightning Resist 75%, 20% Lightning Absorb and Lightning Absorb +20 would apply to 60 lightning damage as follows:
LR 75% decreases 60 to 15
20% LA decreases 15 to 12 (-3)
LA +20 decreases 12 to 0 (-12)
15 (3+12) healing applied
0 damage applied
Player with 45/100 life would be healed for 15 ( min(100-45 , 15) ) life, resulting in 60 (45+15-0) life after damage applied (+15 life).
Player with 90/100 life would be healed for 10 ( min(100-90 , 15) ) life, resulting in 100 (90+10-0) life after damage applied (+10 life).

LR 75%, 20% LA and LA +20 would apply to 180 lightning damage as follows:
LR 75% decreases 180 to 45
20% LA decreases 45 to 36 (-9)
LA +20 decreases 36 to 16 (-20)
29 (9+20) healing applied
16 damage applied
Player with 45/100 life would be healed for 29 ( min (100-45 , 29) ) life, resulting in 58 (45+29-16) life after damage applied (+13 life).
Player with 90/100 life would be healed for 10 ( min (100-90 , 29) ) life, resulting in 84 (90+10-16) life after damage applied (-6 life).
