It does lower damage done to ONESELF , so under chaos you do a surten damage and it lowers by damage reduction.

Idont see why they are having both Defense,that actuallly lower damage done to you and damage reduction doing the same thing.

Still thats what the description says and what you say is pulled from? some dark place iguess ^^
You do a surten damage to yourself (team) when you are chaosed and hit them while chaosed.
