(Terr´Noc lost 2 times 2 DG due to using bloodspikes, and 4 due to starting to regenerate his armor,
So he would be at 37 not 35 DG now, unless I´ve overseen something, feel free to correct me there. then, due to having lost the first 10% of his DG his SG will rise and the received damage in case he is getting attacked will be lower("damage reduction") now, you can choose the values yourself I guess, you should keep in mind though that he gets this bonus another time for every 10% DG lost)
