Ignore Target Defense

[jcvmarques]

Hello

I've seen some posts talking about this mechanic - ITD.

Why is it so useful on bows ? I have a Rogue in Hell with a bow without ITD and I have no problem hitting monsters. Is the mechanic different in this mod ? Does it do more damage also ?

Thank you!

It increases your attack rate slightly and allows you to do more damage by bypassing their natural damage reduction.
Lets say youre playing the original diablo and you walk into hell level 13 with like 100 defense. Notice how fast you die? Walk back with around 250 defense and the difference is noticeable.

ITD is absolutely needed against bosses in Torment.

Why ? How exactly does the mechanic work ?

from my old post.

"ignore target's defence" affix works enemy's armor to 0 on hit-chance and physical damage calculation.

*displayed DPS with Doombringer is higher than DPS with Viz sword.

I guess hit-chance calculation is based on hit-chance calculation of D2.
(because my char with 450% chance to hit fumbles little against torment enemies, especially champs/uniques)

<Hit-chance calculation of D2>
Chance to be Hit = 100 * AR / (AR + DR) * 2 * alvl / (alvl + dlvl)

AR = Attack Rating (my chance to hit)
DR = Defense Rating (= enemy's armor)
alvl = Level of Attacker(= char lvl)
dlvl = Level of Defender (= mlvl)

for example, insert each value...

AR(my char) = 200
DR(enemiy) = 0 (due to ITD)
alvl(my lvl) = 50
dlvl(mlvl) = 70 (its sample valie which start drop qlvl70 gears such as windforce)

= 100 * 200 / (200 + 0) * 2 * 50 / (50 + 70)
= 20000 / 200 * 2 * 50 / 120
= 10000 / 120
= 83.333333 (%)

Torment enemy has high armor.
So ITD is useful (maybe mandatory) for hit chance and physical damage in torment enemies if my thoughts is correct.
