whats the base physical defense and magical defense for each armor type?

Physical is listed here: http://ladderslasher.d2jsp.org/index.php?g=10
The magical hasn't been added yet but I'm sure it will be in a matter of time.

You can just check the market for each tier and type if you really want to find out though

Plate physical = robe magic
Chain Physical = Padded Robe Magic
Scale Physical = Leather Armor Magic
Leather Armor Physical = Scale Magic
Padded Robe Physical = Chain Magic
Robe Physical = Plate Magic
