defense reduction calc order

[Wiz]

Has anyone worked out the order in which -defense mods are applied to arrive at a final defense number? In particular, if you have conviction and Inner Sight in effect, what is the order of application? Now that IS gives a quite substantial subtraction to enemy defense ( ~816 @ level 20 IIRC), it can actually be useful past the first few acts. In particular, if IS or other mods, like the -25% from eth runes, is applied after the %reduction from conviction, it could be very useful indeed -- and it would make Act 1 mercs much more desirable.

Any ideas?

We did a test in early D2 on Inner Sight.

Versus Iron Skin, it reduces the DR, and then Iron Skin is applied.
Same, as I recall, with Defiance. Base DR reduced, then Defiance applied.

I apologize, this is a three year old memory, and from about patch 1.03.

We could probably meet up and go PvP to figure it out, if I get the time. PM me with a time and an IP address for TCP/IP game.
