| Author | Dwarf imunity runes and magic damage |
|---|
Since I find it hard to figure it out, please help me with this:
I had a fight against a wizard who had 29 spell power with 28% magic penetration.
I had:
- 25% magic prof
- barrier
- resistance
- immunity to air
- immunity to water
The wizard cast lighting on me and did 113 damage.
The wizard cats ice cold spell on me and did 83 damage.
So the questions are:
1. Wasn't I supposed to be immune because of my runes?
2. What is the formula behind this? |
| we also need to know which (chaos) talents the mage had |
| 28% magic penetrate immune |
for Sven91:
Mage had:
Advanced chaos magic
Expert sorcery
Mana recovery
Concealed knowledge

Near the end of the battle look at the damage he did to my lava dragons. |
| if youre not concerned about damage calculations, this damage dealt to you was due to penetration , so you only took a smaller fraction of his potential spell damage. |
for 4themassive:
28% magic penetrate immune
How does it penetrate imune? It penetrates for 28%? And how about my other talents (resistance, barrier, 25% magic proof). Are they calculated before or after the magic penetration? |
normally he would have done around 400-450 damage (assuming you'd have minimal magic resist). you had immunity (i.e. 100% magic resist). and he had 28% pierce through magic resist. so he would deal 28% damage.
28% * 100% * 400 = 112
makes sense ? |
cant see the battle due to blindfold, but
29 spellpower + advance chaos => 450 damage lightning, 335 ice clod.
113 of 450 is 25% of regular damage
83 of 335 is 25% of regular damage.
so i guess barrier/resistance/25% magic proof dont help a lot in case of immunities. |
so i guess barrier/resistance/25% magic proof dont help a lot in case of immunities.
That is my guess too, that the talents and magic resistance from AP comes after the immunity. So they actually further protect me from the 28% damage, further decreasing it to 25%.
This is why I asked for the formula that calculates damage in my case... |
as far as i remember magic resist is not cumulative.
so if you're wearing a cape (15%) and the two 20% talents your rests is not gonna be 20% + 20% + 15% = 55%.
it will be:
20% + 20% * (100%-20%) + 15% * (100% - (20% + 20% * (100%-20%)) = 20% + 20%*80% + 15%*64% = 20% + 16% + 9.6% = 45.6%
similarly, when you have 100% resist from immunity the other resistance factor will just be multiplied by 0 so they don't have any effect!
the calculations are:
100% + 20% * (100% - 100%) + .... = 100% + 0% + ... = 100%
and it makes sense this way, otherwise you could have more than 100% resistance. now what would that mean?! get health when struck by lightning?!!! |
| 3% from faction resistance? |
for gmt325gh:
Thanks for the formula, it makes perfect sense.
So for all you dwarfs out there, either use magic resistance talents, or your magic resistance runes. No point in using both ;) |
0.97*0.36*0.72*450=113
0.97 is from faction resistance
0.36 is from the 2 magic resist talents
0.72 is from magic piercing
450 is normal damage output
elemental immunity from the rune has no effect |
| double click the wizard lord and you can see piercing magic % that will force your magic/imune resistance |
| @13: why elemental immunity no effect? |
Sven, I don't think you are correct. 0.36 is indeed from magic resist, but if you're calculating his damage like this, you should take 1-0.36 for that.
It looks very simple to me. You get 100% resistance from the rune. Other resistances don't matter, you can't get more than 100% resistance. Piercing reduces this resistance with 28% and then you also have 3% protection from your faction resistance, summing it up to 25% of the original damage. |
@16: correct calculation is cumulative?
why not 100% resist x 28% penetration x 97% faction unprotect = 27% damage |
| fosgeen, you are right about my mistake but 450*0.28*0.97 is 122 |
| yes i know it is wrong answer but why the model is incorrect? |
with 28% magic penetration.
are you 100% sure?
15% from cape
10% from staff
5% from scroll
3% from necklace
1-(1-0.10)*(1-0.15)*(1-0.03)= 0.25795
1-(1-0.10)*(1-0.15)*(1-0.05)= 0.27325
I do not think it is possible to have 28% magic piercing ?
