Shield of the Eighth DS stacking question

[Triiz]

The Wiki shows you what slot each buff is, assuming it's accurate.

For example

Shield of the Eighth is
Slot 2: Increase DS

Bramblecoat is
Slot 2: Increase AC
Slot 3: Increase DS

So it should stack.

Guardian and Shroud are AC in slot 4, so it should also stack. At least that's my understanding.
