I cant find blood armor in special deliveries chest, please help
You mean the blood dragon armor? There are some bugs for that for the dwarven origins, see: https://dragonage.fandom.com/wiki/Blood_Dragon_armor_set_(Origins)#Exploits_and_Bugs
Im talking about dragon age 2
Then why did you use the Origins tag?
If you have the DLC installed, it should be in the chest in Gamlen's house or Hawke's estate. If it's not there, and reloading doesn't work, try reinstalling the DLC.
What do you think?
