I died with a lvl 100 HC character yesterday, and today I noticed I had tier 3 components in my stash. There is a chance that I did have them in there, but I usually don’t have lvl 3 components laying around and I did have all of those (but more, for example seal of annihilation as well) on my dead HC char.
I did test this with lvl 1 components on fresh chars, and I didn’t get any components back, so this might just be a fluke. I also don’t know how to test this with lvl 3 components. My time isn’t worth deleting 3 or more hours of gameplay to test this.
but, you know, just in case this is something, I wanted to mention it.
