Why does lord dominiks regards even exist?
This item single handedly makes tanks fall off hard late game, that and black cleaver. Not only does it ignore 45% of your purchased armor, it gives a 15% damage boost. That combined with tank shred abilities and bork makes tanks only last like 4 seconds late game, and make it 2.5 seconds if they have vayne. Trust me I played against a vayne with ldr and after that tankiness doesn't exist anymore.
