Damage reduction VS. Crit Multiplier

[Lorkar1]

Does damage reduction occur before or after the critical hit is multiplied?

[DM Sun Tzu]

If done properly, after.

[Lorkar1]

Can you elaborate on "properly" please?

I would think that damage reduction would take place before.
Because you are reducing the damage from one attack and then whatever damage is left would be multiplied.

almost positive dr comes in after the damage is already multiplied.

else a dr 20/- armor would result in 0 damage crits from the appropriate weapon.. which is not what ive seen (i.e. rapier usually dealing 4-5 damage on non crits with a crit dealing 50 damage.)

[Mr. O'Dearly]

Because you are reducing the damage from one attack and then whatever damage is left would be multiplied.

Actually, the entire multiplied damage is one attack.
...and so you should apply after multiplication.
If you were to apply DR before multiplication, it would be like resisting a single attack multiple times.

A crit is not applying damage multiple times. The multiplier is just used to represent how much more powerful a crit is relative to a normal hit.

So you are saying that damage reduction is pointless against crit attacks? I am a little confused now myself.

[Amoenotep]

crits don't add damage after damage is already applied..it multiplies the damage for that attack


damage reduction takes away from the damage dealt by single attacks and therefore reduce the damage taken from crits

[Gornickthy]

Now that makes sense. Thank you.

dr applies against crits. however applying dr20 to an incoming 200 point critical hit maybe doesn't do as much as you like (200 - 20 = 180, still ouch).

This is where damage immunity comes into its own: the bigger the incoming damage the more the immunity % will do for you. 25% immunity -> (200 - 200x.25 = 150, less ouch)

combined on the same item you'd eat 130 damage if i recall the order of operations correctly (immunity then dr). the system is worth paying attention to when you're selecting armor/shield combos for a mixed damage area.
