I don't think you can trade that stuff, can you?I'm not sure if anyone else has been playing this recently, I got back into it since it was on sale on Xbox.
It's a long shot and I may have to check on reddit but I figured I'd ask here first if anyone has a spare Delta Guard on Xbox One that they'd be willing to send my way.
Someone could give you a BB Armour Level 2 (I'm on PS4 sorry!), but it'd be random as to what is in it, you'd need to keep resetting with Godsbane in order to get what you're looking for, and you'll need to head over to Olra at BBI to purify it.
