To understand how INT shield operates we must first establish how intra and Inter modifier stats interact within, and between one another.
-Same type modifiers (Intra) interact with one another additively. For example: If you have a base damage resistance of 25% and you increase it by 10% then you would have a final total damage resistance of 35%.
-Similar type modifiers (Inter) leading to the same outcome interact with one another multiplicatively. We will be looking closely at these type of interactions to evaluate the behaviour of INT shield with the other modifier stats, as it is classed as its own modifier.
General equation for total damage negation is as follows:
Damage negation = 1-[(1-A)*(1-B)*(1-C)*(1-D)*(1-E)*(1-((G*Z)+F))]
Where:
A is the overall damage resistance
B is all-out damage reduction
C is the phys-out damage reduction
D is the mag-out damage reduction
E is the physical damage resistance
F is the magical damage resistance
G is the total INT
Z is the INT shield factor
As you can see there are A LOT of (1-x) factors, they are put in place merely to get our final damage suppression in terms of the damage reduction , as opposed to the remaining percentage of the original damage received (All In). There will rarely be any instances where all of these variables are in play at the same time, and as a result you can ignore all the variables but those relevant to your specific situation. it is important to note that mathematically, the x values in these 'absent' terms would be 0, and hence you'd just be multiplying by 1, which is effectively the same as acting as if said variables were never there.
In the case with the INT shield factor you will by now, I'm sure have noticed that it interacts additively with mag in, more on why this is the case can be found in the INT shield in action section. We multiply the total INT by the INT shield factor (Z) to get the INT shield's effective damage suppression, we do this because we're dealing with an absolute value and wish to convert it into a percentage in order to properly gauge its behaviour. This value is in fact the INT shield factor, that is to say; 1 INT = 0.134% (at level 90) damage reduction from mag damage. This was found initially by finding the total damage suppression and then solving algebraically in terms of INT shield's effect in order to solve for the INT shield factor.
