RO: There are two types of injuries: physical injuries and magical injuries. Is it better for a mage to use a deputy who reduces magic defense or a deputy who reduces material defense? Player? diaalphisto？ It brings us a comparison of the income of mage assistants in the current fairyland legend RO mobile game-15% magic defense and -25% physical defense.
Injury formula
Physical damage = floor ((floor (equipped with ATK+ level ATK) * shape correction * attribute correction)+attribute ATK)*(4000+ monster defense value) /(4000+ 10 * monster defense value))
Magic damage = floor ((INT * 2+ floor (INT * INT/ 100)+ equipment MATK+(INT+ equipment MATK) * MATK increase) * skill multiplier * (1000+mdef)/(1000+)
Ignore all bonuses, and only discuss the DEFensive attributes. The key to the operation of def and MDEF lies in (4000+DEF)/(4000+ 10*DEF) and (1000+mdef)/(1000+/kloc-0 *).
Then draw the income curve of two deputies at will. Assuming that the attack cardinality of ATK and Matek after various multiplication operations is 1000, the formula can be formulated.
x=linspace(0，800)；
y 1=(4000+x)。 /(4000+ 10 * x)* 1000；
y2=(4000+0.75*x)。 /(4000+7.5 * x)* 1000；
y3=( 1000+x)。 /( 1000+ 10 * x)* 1000；
y4=( 1000+0.85*x)。 /( 1000+8.5 * x)* 1000；
z 1 = (y2-y 1)。 /y 1；
z2 = (y4-y3)。 /y3；
plot(x，z 1)；
Hold on;
plot(x，z2，' r ')；
Stall;
Finally, you can draw two kinds of deputy promotion ratio curves to attack, that is, when facing 0-800 magic defense and physical defense, the deputy will be converted into actual attack bonus:
When the intersection is around 225, that is, the target physical defense and magic defense are both 225, the benefits of the two deputies are the same, which is roughly equal to 108.5% of the damage when the deputy is not worn.
Add a 0- 100 DPS income map of physical defense and magic defense, because the mainstream monsters are in this range, you can use your own ruler to see the DPS promotion ratio brought by the deputy? Mark points are used to turn eggs.
Verification: It is known that the magic defense of egg turning is 4 1. After substitution, the calculated gain is about 3.9%. Master 955MATK cracked 955, took off 2926 secondary damage and put on 3033 secondary damage, and the attack increased by 3.656%. Considering the magical rounding of the basic value, this verification is passed.
Conclusion 1:- 15% MDEF deputy refused to be promoted, which makes sense, otherwise it would be against the sky.
Conclusion 2: In the face of BOSS with high magic defense, it is better to install a deputy to reduce physical defense and feel at ease. Sure, maybe you should focus on field control?
