Are there only 6 "Tank Items" That don't deal damage?
Did I miss any items, or is this it for non-damaging tank items that don't qualify as support?

Boots, I didn't really count these.

Support tank, also didn't include.

Split push items, Could have maybe included them, but they technically increase damage.

Tank items that 'add damage', only seven. And some of them hardly "add damage"
