# How does the shadow/lunar resistance on the armor sets work?

## Recommended Posts

I've noticed that when you are wearing a full Brightshade or Voidcloth armor set, they gain additional resistance to lunar-aligned or shadow-aligned mobs, depending on the set.

Problem is I currently don't understand how the math works in terms of armor reduction. Does anyone know how it works?

Let's say that you are wearing BS Helmet and BS armor. That's -25% dmg form lunar mobs.

And you get hit by a Brihtshade 100dmg + 30 planar.

80% of normal dmg is reduced from normal def of BS, then another 25% (from set bouns) form 20dmg left, so that is 15 normal dmg

25%(set) of planar is redced, that is 22,5, and then 20 of planar defense granted by both pieces.

Adding it all up is 15+2,5=17,5dmg

When you have only 1 piece you get 10% dmg resistance.

So 20 normal then 10% of that is 18

and 30 -10% is 27 then -10 from planar def

18+17=35

Tested ingame.

2 clarifications here:

• Lunar/shadow damage resist also reduces damage dealt to armor. For this reason I think it's applied before normal damage reduction rather than after, but I can't say for certain (this would also explain why lunar/shadow damage bonuses don't get the full benefit for physical damage against planar entities, assuming they work the same way).
• Dreadstone for whatever reason doesn't give 25% with a full set, just 2 separate 10% modifiers (which would be 19% combined).
