All the tests I did pointed toward a 0.5*WDEF reduction on normal statted characters, with typical wdef.
If you move farther away from that (pure str magician, 3-400 extra wdef from "typical gear") you can maybe push it to 0.7*WDEF.
Primarily percentage skills will always be the best way to reduce damage. Achilles, Invincible, Powerguard, Hyperbody, the reason they're effective is that they reduce a percent of the total.
Might as well post numbers here...
Lv.38 Fighter against Street Slimes, 191~198 str (White Baseball Cap = +2 str, Fireman's Axe = +7 str)
3 wdef - Versalmas Hat, Black Strap Shoes, Maple Flag:
110-114 damage
64 wdef - White Baseball Cap, Silver Fitted Mail, Black Strap Shoes, Lionheart:
77-81 damage
97 wdef - Brown Bamboo Hat, Silver Fitted Mail, Black Strap Shoes, Lionheart:
59-64 damage
99 wdef - Mithril Full Helm, Sapphire Fitted Mail, Red Snowshoes, Lionheart:
58-62 damage
145 wdef - Brown Bamboo Hat, Sapphire Fitted Mail, Red Snowshoes, Fireman's Axe, Red Cross Shield:
33-37 damage
+61 def = -33 damage = 0.54 damage per def
+33 def = -17 damage = 0.52 damage per def
+2 def = -1 damage (or -2) = 0.5-1 damage per def... (this was mostly changing item class/levels..)
+46 def = -25 damage = 0.54 damage per def
It's pretty well linear for this case :/ I'll log on my Paladin later to do similar stuff, since it has a much wider range of defense.
